Gua Sha that cools every nook and cranny

This is the gua sha I bought a while ago to do a gua sha challenge. I bought it at Daiso for 1,000 won. It is small and lightweight, making it easy to use for massages. I found it better for massaging tight corners rather than large areas. Since applying too much force can cause bruising, it feels very refreshing to press on the desired area with the pressure applied moderately. That is why I continue to practice gua sha whenever I have free time.
