Beaker Bong with Inverted Restriction

This beaker bong by Grav Labs stands at 8.5" tall and has a simple design that packs a surprising amount of functionality. This clear glass beaker contains a fixed downstem with holes to filter and diffuse your smoke for optimal hits with every use. The scientific glass bong 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 glass bong is distributed by Grav Labs here in the USA and is made from thick glass.
