Daiso gua sha is good.

This is a gua sha I bought at Daiso for under 3,000 won. It has a good grip and is reasonably priced. As I push and slide it along, my face looks smaller and it stimulates the lymphatic vessels. It’s great to have one lying around haha. I’m not sure if that exact product is still available, but it’s nice to keep one at home to use while watching TV. Daiso gua shas are good, too.
