Black Accented Beaker Bong with Inverted Restriction

Sold out

This beaker bong by Grav Labs, stands at 8.5" tall and has a simple design that packs a surprising amount of functionality! The fixed downstem features holes that filter and diffuse your smoke, for optimal hits with every use.

This artistic piece has a 14mm female joint and includes a 14mm male bowl!

One of the standout features of this bong is that it contains an inverted restriction that serves two functions. It creates a convenient handle around the neck while also giving this small beaker an ice catcher to cool your smoke.

The flared mouthpiece provides a more comfortable smoking experience while also forming an air tight seal, so no smoke escapes.

This bong is distributed by Grav Labs here in the USA & is made from thick, scientific glass!
