Marble Ball 5mm

Marble Ball 5mm

5mm glass marble ball for bong downstems and dab rigs. The larger diameter creates fewer but bigger bubbles, which some smokers prefer for a less restricted draw. Borosilicate glass construction handles repeated heating and cooling cycles.

Sizing Guide

5mm suits medium to wide downstems. For tighter stems, go with 3mm or 4mm. For the widest stems and beaker bongs, try 6mm.
