Here at The Mushroom, we think skulls are badass. Needless to say, we think this is one badass 14mm skull-shaped water pipe bowl. 14mm bowls are the most common sized fitting for standard-sized water pipes.
The Mushroom only carries products we believe in. This is why most of our glass is made of high-quality borosilicate, the most durable on the market. They won't break if you accidentally set them down too hard, or drop them on the carpet. Buying glass made from high-quality borosilicate is worth it!
