This low-key device has a sleek and slim exterior that gives it the appearance of a traditional disposable vape. The original color line's outer shell is made from quality metal, while the new thermochromic color line is constructed from durable plastic that has a heat-reactive coating. The DL Vape Pen even takes it a step further by granting users full control through the power of breath. Power the pen on and off with 5 quick puffs and change the voltage settings with just 3 quick puffs. The DL also has a pre-heat mode which can be activated with 2 short puffs to prepare your carts for the next rip.
