The Boundless Terp Pen is straight out of a spy movie. No bigger than an ink pen and without any buttons to worry about, the Terp Pen reaches vaping temperature in moments and starts heating up the moment you draw through the mouth piece. The ceramic coils are known for flavor purity and durability, making them top choices for concentrate vaporization. The Terp Pen charges through micro-USB for maximum convenience, providing liquid rig results without butane or a torch. Compact, ultraportable and crafted from durable medical grade stainless steel, the Terp Pen is only 5.5" (140mm) long and fits your pocket perfectly for vaping anywhere and everywhere!
