This is a set of six replacement balloon bags for the Volcano Vaporizer's Easy Valve System. Works with either the Volcano Classic or Digital Vaporizer models.

"I don't know what that happened to my original ones, but I kept losing them or they kept getting stolen from my home. Luckily I found the parts and I got my Volcano back up and running."
