The Boundless Terp Pen Vaporizer has a ceramic coil that heats up almost instantaneously and is activated automatically by a sensor that detects your inhale. Simply apply the coil directly to a small amount of concentrate and you're ready to rip! The amount of vapor produced is entirely up to you. Enjoy short draws or inhale for up to 10 seconds before the automatic shutdown activates. The included magnetic cap allows for quick storage. This easily cleanable pen is slightly larger than your average writing pen, making it ultra-discreet. Equipped with a long battery life, this pen allows for all day use and can be recharged using the included Micro USB cable.
