Clear UPC Cylinder Bowl with Color Marbles

These flower bowls are part of UPC’s premium line of products, designed for those who want reliable and durable smoking accessories. The bowls are built in the USA with super thick borosilicate glass, which gives them greater durability and heat retention. They have a cylinder shape, so you can load as little or as much as you want, without sacrificing efficiency.  The bowls are completed with color marbles for an eye-catching look, and the marbles also work as handles and roll stoppers.  You can choose between 14.5mm and 18.8mm male and female joints.
