The Harmony CBD Pen is the easiest entry into the world of CBD vaporisation. The fully charged battery lasts for up to 500 puffs per charge. The battery is a rechargeable lithium cell that charges approximately 500 times. We recommend not to use the Harmony CBD Pen with cartridges of other brands or old cartridges that have been manually refilled to avoid leakage and bad taste. The Harmony CBD Pen is the best option for people who want to enter the world of CBD vaporisation in an easy and affordable way.
