ROOR Blue Series 500ml Straight Cylinder Bong

Straight up and and down but never boring, ROOR's Blue Series cylinder bong features a stable hexagon base and is constructed from tough, high-grade borosilicate glass. Built to bring you years and years of smoking fun, your bong will arrive ready to go with a sliding funnel bowl with colored glass roll stopper and a non-diffuser downstem for a strong, snappy hit. The ROOR logo in blue is featured prominently, so everyone will know that you know what's up when it comes to glass bongs!

The 500ml version is available with a 14.5mm or 18.8mm joint — choose from the drop down menu when ordering. As a bonus, you'll also receive a free 3-point ROOR glass screen with your purchase!

Founded in the 1980s by German glass-blower Martin Birzle, ROOR produces high-end premium borosilicate glass bongs and smoking accessories, many of which you can find right here on our site!

To verify your ROOR bong is the real deal and not a cheap copy, every ROOR bong now comes with its very own seal, which is like its own fingerprint. Every seal has its own unique tag with 3-dimensional air bubble field and an alphanumeric ID. You can either scan the QR code next to the bubble tag or enter the ID code on the seal at https://roor.de/authenticate/. If yours is the real deal the pattern that will appear after you enter the code is identical to the one on your seal.

All ROOR items are handmade therefore shapes and downstem lengths can slightly vary. We strongly advice to measure the unique length of your downstem when you receive your bong, in case this needs to be reordered.
