Monkey King Pre-Rolled Cones are King Size Slim hemp cones that arrive already rolled, already tipped and completely empty, so the only job left is filling them. The brand states 100 per cent hemp fibre and natural Arabic gum, and the retail pack comes with a packing tool and a small tray, which is not something most three-cone packs bother with. What no page selling these will tell you is why a cone is shaped like a cone at all, what a King Size cone actually holds, or why the one you rolled last week burnt down one side. The best guide we could find on cone sizes runs to about 2,100 words and answers none of it.
What a King Size cone actually holds
Cones come in a standard ladder of lengths, and each rung has a rough fill weight attached to it. The figures are published, but only in trade documents written for people buying by the hundred thousand, which is why nobody shopping for a pack of three has ever seen them.
Here is the ladder. A 70mm cone, known in the trade as a dogwalker, takes somewhere around a quarter to half a gram. An 84mm, the 1 1/4 size, takes about half a gram. A 98mm takes half to three quarters. A 109mm King Size takes about a gram, which is why it is the standard for a full one gram roll.
Monkey King's cone is King Size Slim, and the brand's paper at that size measures 108 by 44mm, so it sits at the top of that ladder. Slim is the qualifier that matters: a King Size Slim is the long, narrow one rather than the long, fat one, so the capacity sits at the lower end of what a 109mm cone can take rather than the upper.
Fill weight is approximate by nature. It moves with how densely the material is packed and how dry it is, which is exactly why the trade quotes ranges rather than numbers.
The full specification for this cone, including the paper weight and the fitted tip dimensions, is set out on our page for the Monkey King tray box, which holds the same cones. We are not going to print it twice.
| Length | Trade name | Typical fill | Roughly |
|---|---|---|---|
| 70mm | Dogwalker, mini | 0.25 to 0.5g | A short one |
| 84mm | 1 1/4, classic | About 0.5g | The common small cone |
| 98mm | Standard or reefer | 0.5 to 0.75g | The middle rung |
| 109mm | King Size | About 1g | The full-size standard |
| King Size Slim, this cone | Long and narrow | Under a full King | Length without girth |
Why a cone is a cone
This is the question the entire category is built on and nobody answers it, including a 2,100-word guide whose only subject is cone sizes.
A straight tube burns badly for a reason you can reason out from first principles. As it burns down, ash builds behind the ember and the channel you are drawing through gets narrower and dirtier. The draw tightens, you pull harder, the ember runs hotter, and the last third is nothing like the first.
A cone inverts that. The wide end is where it burns and the narrow end is where you draw, so the burning cross-section shrinks as the ember travels toward you rather than staying the same. The volume of material ahead of the ember falls away at the same time as the paper circumference does, which is why the draw stays roughly consistent from the first pull to the last.
It also means the largest amount of material sits furthest from your mouth, which is the other half of why a cone stays cool longer than a straight roll of the same length.
The taper is not styling. It is the single design decision that makes the format work, and it is why cones took over from hand-rolled cylinders almost everywhere they are sold.
Canoeing, and how to stop it
Everyone has had one burn down one side and turn into a canoe. It is the most common failure in this format and the ranking set is silent on it.
There are four causes and three of them are yours.
Uneven packing is the main one. If one side of the cone holds more than the other, the loose side burns faster because more air gets through it. The ember follows the path of least resistance and the dense side is left standing.
Wind is the second. An outdoor draught pushes the ember sideways before it can travel forward. Turning your back is a genuine fix.
Moisture is the third. Damp material burns slower where it is damp and faster where it is not, and a lip mark left on the paper is a small wet patch that behaves the same way.
The fourth is the paper itself, and this is the one the format helps with. A very thin paper burns closer to the rate of what is inside it, so it is less likely to race ahead on its own. Monkey King's cones use the brand's ultra-thin hemp paper, and thin unbleached hemp is about the least likely paper to run.
The practical fix for the first cause is the tool in the pack. Fill in stages, tap the cone upright between each, then use the poker to press down gently rather than ramming from the top. A cone packed evenly in three passes almost never canoes.
There is a tray and a poker in the pack
Two independent sources confirm this and neither our distributor's own hemp listing nor most retailers put it anywhere near the top.
Our distributor's listing for the identical Pink version of this three-cone format states that it includes a packing tool and a mini rolling tray in every three-pack. The brand's own UK page for the cones says each three-pack includes a custom Monkey King packing tray and pokers.
That is unexpected. A pack of three cones is a small thing, and a fold-out tray and a poker inside it means the pack is a complete kit rather than a refill. You can fill a cone on the tray, pack it with the poker and put the tray back in your pocket.
Worth being precise about the limits. Both statements describe the retail three-pack format across this cone line. The tray in a three-pack is a small card or plastic item, not the metal tray box the brand also sells, which is a separate product with cone holders built into it.
The tip is already fitted too. The brand describes every cone as coming with a pre-fitted filter tip which gives the roll structure and keeps material out of your mouth. That is the same job a card tip does in a paper booklet, done at the factory instead of by you.
| Element | State it arrives in | Your job |
|---|---|---|
| The cone | Rolled, sealed, empty | Fill it |
| The tip | Already fitted at the narrow end | Nothing |
| Packing tool | In the retail pack, per two sources | Use it in stages |
| Mini tray | In the retail pack, per two sources | Fill over it |
| The seal at the top | Open | Twist or fold it shut |
A cone is not a pre-roll, whatever the search results say
Two words get used interchangeably and they mean opposite things depending on which side of the Atlantic the page was written on.
In UK usage a pre-rolled cone is an empty paper shell. It has been rolled for you and there is nothing in it.
In American trade usage a pre-roll is a finished, filled product sold ready to smoke, and the empty shell is called a cone to distinguish it. That is why searching either term throws up dispensary menus alongside packs of empty paper.
What we sell here is the empty shell. It contains no plant material of any kind, and it contains no cannabinoid either, which is worth saying plainly on a CBD site. Hemp in this context is the fibre the paper is made from. Our Mr Tipp's page sets out that distinction in full, and our catalogue's own mislabelling of paper products as cannabinoid products is a data fault we are correcting rather than defending.
Over 18s only, as with everything in this aisle.
How it sits against the other cones we stock
Cones differ on three things that matter and a dozen that do not. Length, paper, and whether anything has been added to the tip or the wrap.
This Monkey King cone is the plain one. Hemp paper, fitted tip, nothing added, and the tooling in the pack is the point of difference rather than any feature of the cone itself.
The G-Rollz hemp cones are the closest comparison in a similar King Size hemp format. King Palm's natural hemp cones run to a different construction again, and its flavoured lines add a taste to the wrap, which this one deliberately does not.
The brand's own Flavor Burst cones sit at the other extreme, with a squeezable capsule built into the tip. If you want the cone to taste of something, that is where to look. If you want the cone to taste of as little as possible, this is the one.
| Cone | Paper | Anything added | Best for |
|---|---|---|---|
| Monkey King, this page | Hemp, ultra thin | No | A neutral cone with tooling in the pack |
| G-Rollz pre-rolled hemp cones | Hemp | No | The direct alternative |
| King Palm natural hemp cones | Hemp | No | A different construction |
| King Palm flavoured hemp cones | Hemp | Yes, in the wrap | Wanting a taste |
| Mr Tipp's blunt tube | Hemp blunt wrap | No, and a glass tip | Blunt format, reusable tip |
Who should buy something else
If you like control over the shape of what you roll, a cone takes that away by design. The length, the taper and the tip have all been decided at the factory. Papers give it back.
If you carry things loose in a pocket, a rolled cone is a fragile object with air inside it. It crushes. The brand sells a tray box with cone holders precisely because of this, and a crushed cone cannot be un-crushed.
If you want a smaller roll, a King Size Slim is the wrong end of the ladder. An 84mm cone at around half a gram is a completely different proposition, and nothing about a long cone can be made short.
If you want the wrap to add a flavour, this one is built not to. Try the flavoured cones instead.
And if you have never packed a cone, expect the first one to be uneven. Use the tool, work in stages, and accept that the technique takes two or three goes to settle.
Frequently asked questions
- How much does a king size cone hold?
- About a gram for a standard 109mm King Size, though a King Size Slim like this one is narrower and so takes less. The trade ladder runs roughly 0.25 to 0.5g at 70mm, half a gram at 84mm, half to three quarters at 98mm, and about a gram at 109mm.
- Why is a cone tapered rather than straight?
- So the draw stays even. A cone burns from the wide end toward the narrow one, which means the burning cross-section shrinks as the ember travels rather than staying constant. In a straight tube the channel narrows with ash instead, so the last third smokes nothing like the first.
- Why do pre-rolled cones sometimes burn down one side?
- Uneven packing, in most cases. A looser side lets more air through, the ember follows it and leaves the dense side standing. Draughts and damp material do the same thing. Filling in stages and pressing gently with the packing tool rather than ramming from the top is the fix.
- What is the poker in a Monkey King cone pack for?
- Packing the cone evenly. You add material in stages, tap the cone upright to settle it, then press down lightly with the poker before adding more. Doing it in passes rather than filling and ramming is what stops the cone burning unevenly later.
- Do Monkey King cones come with the tip already fitted?
- Yes. The brand states every cone arrives with a pre-fitted filter tip at the narrow end, which gives the roll structure and keeps loose material out of your mouth. There is nothing to fold or insert, unlike a paper booklet where you build the tip yourself.
- Is a pre-rolled cone the same as a pre-roll?
- Not in this context. A pre-rolled cone is an empty paper shell that has been rolled for you. In American trade usage a pre-roll is a finished filled product sold ready to smoke. What we sell is the empty shell with nothing inside it.
- Can you store a part-used cone?
- Not well, which is a real limitation of the format. Once lit, a cone has an open burnt end and no way to seal it, so anything left in it dries out and tastes stale. Cones suit finishing in one go, and a smaller size is the honest answer if that does not suit you.
- What size is a Monkey King pre-rolled cone?
- King Size Slim. The brand's paper at that size measures 108 by 44mm, so it sits at the long end of the standard ladder while staying narrow. Our page for the Monkey King tray box carries the full cone specification including paper weight and tip dimensions.
