Herbalizer Squeeze Valve Balloons - 4 Pack
The Herbalizer’s Squeeze Valve balloon system is simplicity defined. Squeeze, attach, and fill with pure, flavorful vapor. When you aren’t squeezing it, the valve seals in the vapor so you never loose a wisp. It is made of medical-grade silicone, feels smooth, and is quiet – no loud crinkly noises.
