GRAV Labs Upline Hammer Bubbler

This is one of the biggest hammer bubblers we have available in our online head shop. This bad boy measures about 8 inches long from end to end and stands about 4.5 inches tall. It has an all clear finish for a clean, scientific glass look. The bowl on this hammer bubbler is very good size so you are able to load lots of material.

Empire Rolling Papers

The best for even burn with no added taste. Pure joy to roll a doob with.

Great Bong

I love almost everything about his bong with the exception of the very small bowl which appears large but it has a very small interior space to fill.
Overall, I would recommend this bong to anyone!

We are glad you like the bong! Sorry about the bowl that comes with the bong, they do vary in size. We do have larger round bowls that hold more material.
