My own money purchased Gua Sha product

I ended up buying a gua sha for the gua sha challenge, but I ended up buying the wrong product.

I made a mistake in judgment. I guess I shouldn't have bought it, no matter how cheap it was.

This is a gua sha for Daiso.

It might vary from person to person, but it didn't work for me. I've just been leaving it sitting around. I plan to repurchase a different gua sha product and use it diligently

I'm currently using one. No matter how cheap it is, I think you really need to compare prices carefully before buying. Please recommend an effective gua sha product.
