The Best Filter Tip Size Is 12mm. Here's Why.

Das Filter 12mm, 12 mm Sample

Quick answer: We think 12mm is the best filter tip size for anyone rolling king size, cones, blunts or hash holes. A 12mm tip gives the widest draw, holds the mouth end firm, and leaves room for bigger rolls. We designed our 12mm (12mm x 30mm) for exactly that. If you roll slim or 1 1/4 papers, size down to 6mm–8mm.

Yes, we sell it. Here's the honest case.

Why 12mm?

  • A wider draw. A wider channel means less effort per pull than a narrow tip in the same roll.
  • A firm mouth end. A wide tip fills the end of a big roll, so the paper doesn't pinch or flatten around it.
  • Built for big rolls. King size cones, blunts and hash holes need a wide base. A thin tip leaves gaps and lets the end collapse.
  • Less clogging. A wider opening takes longer to narrow from residue or loose bits than a slim one.

Full fit details are in the filter tip size guide, and rolling around a wide tip is covered in 12mm filter tips.

Made for hash holes

Hash holes have a core of rosin or hash, so they're usually rolled fat. A 12mm tip matches that width and gives a solid base to pack around. See how to roll a hash hole for the method.

Who should size down?

12mm isn't for every roll. Pick a narrower tip if:

  • You roll single wide or slim papers (6mm Slim Jim).
  • You roll 1 1/4 and want a slim finish (7mm Midway or 8mm Big Boy).
  • You prefer a tighter, slower draw.

How to try it

Not sure yet? The 12mm sample is 2 tips for $6. Once you know you like it, the 20-count 12mm box is $25. For regular use there's an 80-count bucket ($80) and a 240-tip case ($200).

Frequently asked questions

What is the best filter tip size?

For king size, cones, blunts and hash holes, we think 12mm. For slim or 1 1/4 papers, 6mm to 8mm fits better.

Is 12mm too big for a joint?

Not for king size or bigger. It's too wide for single wide and slim papers.

How big is the Das 12mm tip?

12mm wide and 30mm long, in a 2-count sample, 20-count box, 80-count bucket and 240-tip case.

Do 12mm tips work for hash holes?

Yes. Keep the concentrate about 1cm short of the tip.
