The Milk Carton Pocket Bubbler takes a familiar shape and turns it into one of the most functional pipes in your collection. Square base, peaked top, a spout where the spout should be. It's a dead ringer for a real carton, except this one's filled with water instead of 2%.

Inside, the bubbler delivers the same smooth, cooled hit you'd expect from a full-size piece, just scaled down to something you can easily carry.

Available in Clear plus five GRAV classics: Smoke, Light Cobalt, Amber, Pink, and Lake Green.
