The KandyPens Crystal Black is a concentrates-only pen. The device features an all-stainless steel exterior and holds an internal 900mAh battery. The device uses a coil-less, all-quartz atomizer and convection heating.
The Crystal Black has a glass mouthpiece that attaches to the stainless steel top cap. The top cap is threaded so users can easily remove it to access the oven underneath. The unit consists of three main pieces: the top cap, the atomizer, and the battery.
Airflow vents line the exterior of the atomizer, providing excellent vapor quality. The Crystal Black also has four separate power settings, indicated by the LEDs down the front of the unit. The power levels run from 2.6V to 4.2V.
The four LEDs on the front also show battery life. Users must click the button five times to activate it and press three times to change the power setting. The Black also comes with a Sesh Mode that powers the atomizer for ten seconds.
