Hamm’s Outside In Bong Full Size | Hamm’s Waterworks OSIB Thin Wall Clear

The outside-in bong by Hamms Waterworks is a staple of scientific functional glass art. Standing at 13” tall, the OSIB has an incycycler recycler that chugs like a beast. Water splash is not a thing with this piece, because the mouthpiece of the piece is the splashguard itself. It’s kinda like a bong inside of a bong. It’s hard to describe, but it absolutely shreds. This is one of the “thin walled” versions, meaning it has a lighter, more mobile feel with a lower price. This piece is a clear 13” version of the OSIB by Hamms Waterworks.
