The Yocan Evolve Plus XL is a revamped Evolve Plus that takes many of the same great components from the original and combines them with some new and exciting features to deliver an extremely efficient and convenient device that is guaranteed to impress. Yocan completely eliminates the traditional thread design found on most pen style devices and replaces it with an ultra-convenient magnetic connection. Never again will you have to waste time trying match together residue-filled threads, simply refill your device, drop the cap back into place and the internal magnets will do the rest.
