Rolling papers

We'll only email you about this product — no marketing.
OCB X-pert Slim Fit rolling papers are ultra-thin king-size papers built for rolling long, generous smokes without the paper getting in the way of your blend. Made by OCB — a French brand that's been producing rolling papers since 1918 — these 110mm sheets are almost transparent, burn slowly, and use 100% natural Arabic gum along the seal strip. If you like your rolls fat and your paper barely there, this is the booklet to reach for.
Everything you need at a glance — no guesswork, no surprises when the booklet lands on your doormat.

These papers don't come with tips. Grab a pack of filter tips or a rolling tray to keep your setup tidy. If you're after an all-in-one solution, check out OCB's combo packs that bundle leaves with cardboard tips — saves you rummaging through drawers mid-roll.
There are dozens of king-size rolling papers on the market. So why do people keep coming back to these? Three reasons: thinness, burn, and taste — or rather, the near-total absence of taste.
The X-pert line sits at the thinner end of OCB's range. Hold one up to the light and you can practically read through it. That thinness means less paper combustion per drag, so you taste your blend rather than the wrapper. The slow burn is the other half of the equation — nobody wants a paper that races ahead of the cherry and wastes material. At 38 mm wide and 110 mm long, you've got proper king-size real estate, which gives you room to pack a generous amount without having to wrestle with a cramped roll.
The Arabic gum strip seals cleanly with a single lick. No second pass, no peeling corners five minutes later. We've stocked OCB for years and the consistency booklet to booklet is one of the reasons they stay on the shelf. You know exactly what you're getting every time.
Here's the trade-off with ultra-thin papers: they're less forgiving. If you're still learning to roll, the X-pert can tear when you tuck, especially if your fingers are damp or you're applying uneven pressure. A thicker paper like the OCB Premium or even a standard RAW Classic is more beginner-friendly because it holds its shape while you work. The X-pert rewards a confident, practised roll — it doesn't babysit a sloppy one.
Also worth noting: no tips are included. If you're used to combo booklets with perforated cardboard tips built in, you'll need to source those separately. Not a dealbreaker, but something to add to the basket if you don't have a stash already.
OCB makes several king-size lines and they all serve slightly different preferences. Here's how the X-pert Slim Fit stacks up against two common alternatives.
| Feature | OCB X-pert Slim Fit | OCB Premium Slim | OCB Virgin Slim |
|---|---|---|---|
| Paper Thickness | Ultra thin | Thin | Ultra thin |
| Material | Natural paper | Natural paper | Unbleached brown paper |
| Size | 38 x 110 mm | 44 x 109 mm | 44 x 109 mm |
| Leaves | 32 | 32 | 32 |
| Tips Included | No | No | Available in combo packs |
| Burn Speed | Slow | Medium | Slow |
| Best For | Experienced rollers wanting minimal paper | Everyday rolling, all skill levels | Those who prefer unbleached, natural look |
The X-pert is narrower at 38 mm versus the more standard 44 mm — that's the "slim fit" part of the name. If you like a tighter, more cigarette-shaped roll, that 6 mm difference matters. If you prefer a wider cone, the Premium or Virgin lines give you more room to flare out.
Ultra-thin papers reward a light touch. Here's the method that works best with these specific sheets.
We've been stocking OCB since the early days of the shop, and the X-pert Slim Fit has a loyal following. The customers who buy these tend to buy them repeatedly — it's a "found my paper" kind of product. The most common feedback we hear is about how little you taste the paper itself. One regular described it as "rolling with air." That's a slight exaggeration, but it captures the idea.
The one question we get asked most: "Are these the thinnest OCB makes?" Close, but not quite — the OCB Ultimate is even thinner. The X-pert hits a sweet spot between transparency and workability. If you want the absolute thinnest paper on earth and you've got the rolling chops to handle it, the Ultimate is your next step. For most experienced rollers, the X-pert is thin enough to disappear and sturdy enough to not fight you.
According to a study on the elemental composition of commercially available cannabis rolling papers, the material composition of papers can vary significantly between brands, with some failing heavy metal testing above action limits (PMC11064008). OCB's 100% natural paper and Arabic gum formulation keeps things straightforward — no unnecessary additives, no mystery ingredients.
Honestly, not the best starting point. The ultra-thin paper tears easily if your technique is rough. Start with something like OCB Premium Slim or RAW Classic — both are more forgiving. Come back to the X-pert once your tuck is consistent.
Each leaf measures 38 mm wide by 110 mm long. That's king-size length but narrower than standard king-size papers (typically 44 mm). The result is a slimmer, tighter roll.
No. The booklet contains 32 leaves only. You'll need to buy filter tips separately or make your own from cardboard. OCB does sell combo packs in other lines if you want everything in one booklet.
Both are ultra thin, but the Ultimate is OCB's thinnest paper — almost impossibly delicate. The X-pert is slightly more robust while still being near-transparent. If you can roll well with the X-pert, the Ultimate is the next level of thinness.
The X-pert Slim Fit papers are white, which indicates processing, but OCB states the material is 100% natural. If you specifically want unbleached brown paper, look at the OCB Virgin line — same quality, no bleaching.
32 leaves per booklet. At one or two rolls a day, a single booklet lasts most people a couple of weeks.
Usually it's moisture or pressure. Wet fingers soften ultra-thin paper instantly. Keep your hands dry, use a lighter touch during the tuck, and don't overpack. The less material you force into a 38 mm width, the easier the roll.
