About Rox Glass Diffusion Stones - Medium
Rox Diffusion Stones split your water-filtered smoke into tiny bubbles, allowing for it to cool and filter more effectively, allowing your hit to be incredibly smooth! These stones are made with art glass, which are softer than the borosilicate glass used in pipes. They are non-toxic and odorless, so your smoke won't be negatively affected. They also help keep your pieces clean by collecting particles that are already in the water, however they can easily be reused and washed with hot water.
Freeze the Diffusion Stones and put them in to your water pipe to create the coolest smoke you've ever experienced. Unlike ice, these stones will not melt and raise your water levels.
Try them out! We recommend the Medium and Large packs for waterpipes with large beaker bottoms or round bases, and the Small packs for straight tubes.
