Upline Hammer Bubbler
This hammer bubbler from the Upline section of Grav Labs is a great choice for any smoker under the sun!
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 located 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. The logo color is chosen at random.
