Please recommend a good gua sha product.

I'm using a pink gua sha sold at Daiso.

It feels a bit irritating, so I'm not using it on my face.

Please recommend a gua sha that isn't too expensive but reasonably priced.

I hope it is a product that is good for the scalp and skin.

I feel like using Gua Sha these days is good because it improves my blood circulation.
