SNOW FOX SKIN CARE Black Gua Sha (Hot Stone) ¥6050 (tax included) Used a few times. Please purchase if you don't mind some minor scratches or signs of use. (The instruction manual also has a fold.) [Product Description] The obsidian used in the black gua sha is a glassy power stone created when volcanic lava cools rapidly. Because it is born from a volcano, it retains warmth for a long time and is ideal as a hot stone for massage. If you put the black gua sha in a glass of hot water beforehand and then massage, the soft warmth containing the deep infrared rays of the black gua sha will increase. The "comb" shape of the gua sha has been continuously improved over thousands of years in ancient China, and it has the optimal shape for conditioning the face. The design allows for two patterns of approach: four touch point surfaces and a flat surface. The thin thickness realized by hand carving stimulates the skin's pressure points with pinpoint accuracy, tightening the skin and at the same time, an anti-aging effect can be expected. #SnowFoxSkincare #SNOWFOXSKINCARE #GuaSha #BlackGuaSha #HotStone #Obsidian
