The offered Roller crystal is very effective and made available by us for use. The offered roller is a beauty tool that has a polished, rounded crystal attached to one end, for use on one's face. The tool often has dual ends, with a long oval-shaped stone on one end for the flat planes of your face like your cheeks, forehead and chin, and a smaller, rounder stone on the other end for under-eye areas, nose and eyes.
