hyunissiThis ring-shaped gua sha tool is great! No matter how much lotion I apply, it doesn't slip thanks to the handle, so I can use it accurately on the desired areas. The size is just right, allowing me to massage anywhere from my scalp to my feet. The pressure is surprisingly good, so I don't have to exert much effort at all. Especially on the eyebrow line and the trapezius area, it feels really refreshing and nice.
