Empire Glassworks Custom Puffco Proxy Ball Cap

These Empire Glassworks ball caps sit on the chamber of the Puffco Proxy and steer air across the concentrate as you turn them. They are made of borosilicate glass and shaped by hand one at a time — among the designs are an avocado, a bee hive, a donut and a galaxy version. In function they match the cap that ships with the Proxy; what differs is the shape of the ball and the fact that handwork makes every piece come out slightly different.
