Brought to you by WoGP the very compact the GRAV Labs’ Circuit is another great invention to add to your ever growing collection. The 6.3 inch Bubbler is blown from state of the art double-layered Borosilicate glass, at a thickness of 5mm it can do the rounds with as much heat as you’ll throw at it with ease and be durable in case of any little mishaps.

Lighting up, the smoke passes through the downstem to a glass Propeller percolator, giving you an extra layer of filtration guaranteeing a flavourful but smooth and gentle hit on your throat and lungs. Combined with its spacious beaker base, your smoke has plenty of space to cool off, spin and get chilled, further refining your hit making it an absolute favourite over straight-tube style bongs. 

Your order also comes with a matching 14.4mm glass bowl with plenty of space for your herb (even dry!) all while avoiding the usual aftertaste of other low quality bowl materials all at a handheld size, so if you were thinking about adding this piece to your arsenal for group settings or long seshs you just hit the jackpot with the GRAV Labs’ Circuit.
