Toke Stone for Blunt-Sized Pre-Rolls

First off, I want to mention that this is a quality item. You can tell it's handmade from one piece of onyx because of the holes being a little off center for each one (I got two) which seems to have been chosen by the crafter(s) for structural integrity.
As long as you have a wide enough diameter for your blunts and joints, you can easily slip one in and it'll pull nice and airtight. My friend's husband accidentally thought it was a piece and smoked directly out of it, so it does handle heat well, lol. Just isopropyl for cleaning from the resin and gunk build-up.
