Heart-shaped gua sha for defining facial lines

This is my favorite gua sha tool. I heard it is made of jade, and since the surface is smooth and soft, it causes absolutely no irritation when rubbing it on my face. It is heart-shaped, so it is convenient to use as I can rotate it to work on different parts of my face. I love how just rubbing it a few times in the morning makes the puffiness disappear completely. Also, after using it for a long time, I felt like my jawline was becoming sharper. It comes with a cute pouch as a set, making it convenient to carry around when traveling. If you search for "heart gua sha" on Naver, you can find a variety of colors, so I like that I can choose the one I like best.
