The inline perc coupled with the cooling power of the coil perc makes for milky, soft hits that are freezing cold. Instead of using ice with an ice catcher, this glass bong has a fun coil percolator. Coil percs work by giving the smoke more time to cool down. The most unique feature of this piece is that it comes apart so you can pop the top half in the freezer for even colder rips plus easy storage. Blown from baby pink and transparent heat-resistant glass, the Pink Coil Inline Perc Rig comes equipped with a matching pink and clear smoking bowl.
