Handmade in California, the RAW Cone Bubbler is made from extra-thick borosilicate glass with an etched conical cone holder (so your cone won’t fall out.) It also has a unique water-break ridge to stop water splashes from escaping the chamber. The RAW Cone Bubbler is designed for one purpose: FUN! It’s insane and really makes you smile. 🙂 Handmade in the U.S.A.
