The K Pen Aqua Bubbler is a glass attachment consists of a small percolation chamber and a K Pen ceramic atomizer.
This will allow you to vaporize even smoother, as the vapor filters through the water each time you inhale.
The glass pieces are made and adjusted to fit the ceramic coils. In general, all vaporizer heating elements transfer heat to the surrounding parts. Due to this, the rubber pieces used for adjustments expand/shrink slightly. To avoid any accidental damage, we recommend to use twisting motions to place the glass attachments onto the coils. Do not apply pressure.
