Art glass is known for making high-quality bongs at an affordable price point and this time around they have made this beautiful bong called The jackknife. It's a classic cylinder bong that got a really simple and trusted design. It’s made out of borosilicate glass and has a bent neck to make it more ergonomic to use. To even further make the user experience better you can also add a few ice cubes to cool you hit down, they will stay at the “bend” of the stem and make the smoke smooth during your session. This Art Glass bong is made out of glass that is 3.5mm thick and it’s very uncommon for a bong this cheap to have that thick glass. It makes the piece both feel solid when holding it also makes it actually more durable if you happen to drop it. This is the perfect piece for beginners looking for an unusual starter bong. It’s also perfect for established bong fans who want to expand their collection with a more unusual piece.
