Raw Glass Tips Round. The RAW Glass tip makes for easy rolling while maintaining the ‘glass effect’. The glass effect is the beautiful feeling of glass on your lips which isn’t absorbent like paper. This way you get to enjoy the best rolling paper in the world (which is the best way to smoke in our opinion) combined with a smooth cool glass tip on your lip.
