The rose quartz roller and gua sha scrap tool by ProCIV are absolutely wonderful. Giving your face a massage gently and effectively. The gua sha scrap tool is my favorite part though. It is an amazing massage tool for the rest of your body! As long as the person giving the massage with the gua sha scrap tool isn't to rough while doing it, it is very relaxing. It worked out a bunched up muscle in my back wonderfully!
