Gua Sha, great for loosening tight jaw muscles~

Rosewood gua sha isn't that expensive, but it seems to be quite useful.

I bought this to relax my jaw muscles, but when I used it to massage my husband's back muscles, he said it felt refreshing.

The shape has a good grip, so my hand doesn't hurt much considering the amount of time spent, and the part touching the skin doesn't hurt either, making it great to use.
