Roll up with OCB the natural way! These rollers are made from plant composite, making it extremely durable, and an environmentally-friendly alternative to plastic rollers. With the roller open, simply fill up your roller with ground herb with a filter tip on one edge, and pack it down. Close the roller and insert the non-adhesive side of your paper into the middle. Moisten the adhesive, then roll with your thumbs toward you, and BOOM! You've crafted the perfect joint in no time.
