The 6.75-inch tall Brain Freeze is a compact oil rig by Evolution that pumps out a lot of percolation power thanks to the slitted showerhead diffuser that's onboard. This robust little rig is equipped with a 14.5mm male joint and comes with a banger nail and a female vapor dome with a handle for easy lifting. 

This rig is made of thick and durable boro glass. It looks like a frozen slushie drink. You know the kind that gives you brain freeze when you take a big gulp. It's a uniquely designed rig supported by a stable round foot.

The colored glass accents throughout the piece look amazing as does the golden Evolution decal on the clear glass base. The accent colors come in several choices. Pick the one you like the best and get your own Brain Freeze so you can enjoy smooth flavorful rips of your favorite concentrates.
