Grav Labs Upline Hammer Bubbler

This hammer bubbler from the Upline section of Grav Labs is a great choice for a daily driver. Made entirely out of clear glass, the Upline Hammer Bubbler has the trademark forced stacked percs that are found in all Upline products. These percs can be found circling the diffused downstem and at the end of the neck towards the mouthpiece. There is an Upline logo brandished on the front of every bubbler. Logo color is chosen at random.

clear glass
This piece features sleek and clean clear glass that allows you to watch this concentrate rig or water pipe function. Clear glass allows you to watch the bubbles stack as your smoke/vapor percolates
deep bowl
This pipe features a deep bowl to allow for a large amount of dry herbs or tobacco to be packed at one time
fixed downstem
The downstem is a glass tube that funnels smoke from the bowl towards the bottom of the bong. This specific type of downstem is fixed into the joint and functions as a perc by distilling smoke with its slits or holes
scientific glass
Scientific glass means this pipe is made from a clear borosilicate glass. It features a “laboratory” design, and usually an overall shape that resembles scientific equipment (glass beaker chambers, straight tubes, etc.)
