Wilding gua sha stainless steel facial massaging tool.. sturdy.. can be sterilized in between uses because it is non porous.. cools/warms quickly.. nice weight to it.. won’t break or rust.. great product :) I have owned several tools from this company and they are all not only high quality but work great! Please feel free to ask questions and make reasonable offers :) retails for 159$ new.. only used this particular gua sha massager a few times :) thanks!
