Glass Bubble Base Mini Tube - Fumed Cobalt Blue Glass
This miniature tube is made by hand from high quality, cobalt blue borosilicate glass that has been fumed, so it will appear to change color over time as resin buildup collects inside. Thorough cleaning will return the glass to its original hues. The glass bowl is held in place by a black rubber grommet and is just big enough for a couple of tokes. It's a cute little piece — effective, portable and made just for you when your order it! Because each piece is individually handblown by glass artists in an Oregon collective, the mini tube you receive will be one-of-a-kind.
