Blaze Glass - Shower Perc Diffuser Adapter Downstem - 29.2mm > 18.8mm

This one piece from Blaze Glass serves as both a diffuser and an adapter! The diffuser end features a 10-slit circular perc for bubbling in every direction, so you'll get a silky smooth, cooled and filtered bong hit! Made of matte frosted glass, this piece was originally designed as part of the Blaze Glass Circ Perc Downstem Precooler With Adapter, but can be used to add circular perc diffusion to any bong or attachment! The inside-cut, sure-ground glass-on-glass joint adapts a 29.2mm joint to any bowl or bong attachment with an 18.8mm joint.
