I like it alot.

Super, very well packaged and fast, excellent material. I just wish the stone had a more pronounced peak so that it fits better on the face.

very good product, good quality. fast delivery. just like in the photo. very useful. highly recommended.

Apparently it is stone
I ordered the small one because the large one was out of stock.
I will try it out.
The size is good for my face and I think I paid a fair price.
It arrived in excellent condition and ready to use.

Looks like a quality product, I recommend it...
