But among them, I'll only introduce the ones I think are bitter, refreshing, and good.
It had a good grip and was great for loosening up my arms, legs, and shoulders.
I recommend it for the body rather than the face.
There are some small ones and some big ones.
I bought a small one because I use it to relax my face and temporalis muscles.
It feels more stimulating because of the bumps.
However, the price is a bit expensive.
There is also a risk of it breaking.
It feels refreshing to massage and loosen up the area at the back of the neck where the hairline starts. It doesn't seem like it's meant for the face, but it's good for a light loosening, so I recommend it.
