Step into the Matrix with this futuristic bong that will add some serious style to your smoking stash! 7mm-thick borosilicate glass creates a sturdy foundation for the body, which consists of a wide chamber and a 9"-long neck. Matrix numbers are engraved into the chromatic neck, available in Rainbow or Silver, which gradually fades into the clear chamber. Another subtle touch is on the base of the chamber, where frosted etching of an arrow pattern surrounding a Gili Glass logo lies. The diffused downstem does wonders to filter and smooth out your hits, while you can also pack the neck with ice cubes.
