The verdict is crystal clear, the KandyPens Crystal Vape is one of the best concentrate vaporizers on the market right now. In 2020, this award-winning vaporizer was named in top smoking magazines, Vaping 360, The Vape Guide, and The Vape Critic, as the best dab pen of the year. It's obvious why. The KandyPens Crystal dab pen burns clean with absolutely no glues, wicks, dyes, or coil and instead is made from medical-grade electro-plated stainless steel with a quartz atomizer and glass mouthpiece. There are 4 power settings to choose from (2.6V, 3.0V, 3.6V, 4.2V) based on your concentrate type and smoking preference. Each dab pen has 510 thread and holds 0.1 grams of material at a time.
