This piece comes with a 10mm Cup Bowl, but can be used with a 10mm banger or a pre-rolled joint, blunt or Dynavap!
I appreciate this little unit. Definitely helps smoothen the hits. If you're in a situation like me, where you can't really have some big unit sitting out, this thing can fit into a lot of cases and be put away easily. Nice compliment to my DynaVap.
