The STAX collection by Grav Labs is one of their most ambitious bong collections yet. So what is a Stax bong exactly? Glad you asked! With completely modular pieces, the STAX bong line is sure to impress anyone. Grav Lab’s awesome modular water pipe system is a series of fully interchangeable thick, high-quality borosilicate glass bong bases, filters, and mouthpieces for those that love to mix and match their own bongs. Grav Labs is well-known for using laboratory-grade scientific glass that means durability and longevity. How do you create one of these, you may be asking? You can simply start by choosing what you are after - either a glycerin coil, a helix mouthpiece or the you-can’t-lose-with-a-classic beaker base then build from there! Each base comes with Grav Labs classic inside-cut 14.5mm showerhead diffuser downstem and a 14.5mm clear glass funnel bowl. What we love about the Grav Labs STAX bong collection is the possibilities are truly endless. Want to make your Stax bong as tall as a tower? Need more diffusion? Add more filters! Want a little cooler smoking experience? Try adding a fantastic glycerin coil to your new STAX bong and you’re good to go. The sky is truly the limit when creating your own customizable STAX bong.
