We use state-of-the-art CCELL cartridges to house our premium cannabis oil. CCELL's ceramic heating element eliminates the burning taste other cartridges can have. The holes in our CCELL cartridges are double the size when compared to other cartridges. This allows for a better flow, easier pull, and nearly 0% clog rate- meaning no wasted oil. Our CCELL cartridges work on all standard threaded batteries.
