Boundless Terp Pen Crushed Quartz Coils – 5pk

The Boundless Terp Pen Crushed Quartz coils are made of high-quality quartz with an embedded heating wire to hear the coil from the inside out. Eliminate any contact between wire and concentrate to enjoy delicate concentrates such as rosin. The coil is instantaneously heated when the breath sensor is activated, allowing you to dip the coil into a concentrate of your choice and enjoy. These coils heat up slower than the ceramic coils and may be best for those looking for a lower temperature experience. It is recommended to preheat the coil prior to applying to concentrate for a medium – high temperature experience.
