The Yocan Evolve Plus is a great wax pen-style vaporizer made with comfort and compatibility in mind…not to mention user friendliness! The Evolve Plus is a bigger version on the Evolve. It has all the same great features of the Evolve, and more! Bigger coil and bigger battery and a conveniently built in silicone wax storage jar on the bottom, are the main differences. Like the Evolve, the Plus pen-style wax vaporizer also is designed so that you can replace coils, when needed. Great for daily use for someone wanting something small and discrete, and for that person who’s always on the go! The Evolve Plus is designed with purity in mind, and is ideal for producing a very pure, potent, and flavorful vapor. This pen-style wax vaporizer comes with a crystal clean dual quartz coil. Ideal for vaping wax concentrates.
