Assorted Gas Mask w/Vibrant DesignWhether youre a plumber, a tennis star, an epic go kart racer or just here for the party this gas mask is made for you! The water pipe is an acrylic material, making it lightweight and easy to cart around while the bottom is shaped like a sassy skull. Easily remove the base for cleaning, but make sure its popped back on tight for smoke sessions. A threaded aluminum bowl and downstem can be removed for cleaning or replacing if its that kind of day.
