This is the Body Formula Ceramic Gua Sha. In the past, whenever my body was stiff, I always used my hands to loosen it up, but I felt there were limitations. So, while looking for ways to reduce swelling, I came across Gua Sha. I felt this product was just right—neither too cheap nor too expensive compared to other tools. I liked it even more because it felt detailed, with different tools for loosening knots in specific areas. I recommend Gua Sha to anyone whose body feels very stiff. Also, please note that if you purchase it on Coupang, it comes with a pouch and offers Rocket Delivery.
