Grav Labs 4" Glass Blunt
The glass blunt is the perfect solution for when you don't want to roll one. The inner tube features a tight rubber seal that lets you slide it back and forth in order to fill the chamber. Push the inner tube to push the ash out as you smoke. The best part about this "blunt wrap" is that it's reusable! Give it a good cleaning every once in a while and it'll last forever. Designed and distributed by Grav Labs in Austin, TX using high grade scientific glass. Measures 4" long.
