Gua Sha items that relieve fatigue

Lately, it's been so hot during the day and getting cold in the mornings and at night, so for some reason, I feel more tired and exhausted.

I've been standing and working for long periods, so I have tight muscles and fatigue. I tried using a gua sha tool I bought a while ago.

It's fine on the face, but it's too uncomfortable to use on areas like the calves, thighs, or arms.

So, this is a gua sha item I snagged at Daiso. That round part moves around and around.

If you hold the handle and gently rub it over tight muscles, the ball moves to relieve the fatigue and muscle tension accumulated throughout the day.

It feels so good to loosen things up and feel refreshed. It is especially great for using all over the body, compared to the 1,000-won gua sha item from Daiso.

It's convenient, so I think it would be good for managing thick calves that swell easily.
