The stone doesn't get warm too fast, so massage is quite pleasant and relaxing ritual.
I also like the package, it is comfortable to keep the roller in it
Its quality is the hardest and can be used with insomnia oil, which is very beautiful for the skin. The size is small, the life is long lasting. You like my comment. Give me a like. God willing. You will like it as much as I like it. God willing, you will like it as much as I liked it.
