Boundless Terp Pen Replacement - Crushed Quartz- 5pk

Our 5 pack of Terp Pen Crushed Quartz Coils are made up of high-quality quartz material, which contains embedded heating wire to heat 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 for you to dip the coil into the concentrate of your choice and enjoy. *Please note that 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. Construction: Crushed quartz with embedded wire.
