They are quite small but for a quick massage on the go or while travelling this is great. The metal roller provides a cooling effect

it's so cute and mini home spa set

Perfect skin care tool duo. Makes the perfect giftable set

The metal roller is great, it is cold and heavy and does leave a nice feeling on the skin. The other roller, however, squeaks and feels very cheap, also it is very difficult to find the right pressure since if your press it too much or too little it simply does not roll.

I have found these rollers to be very useful in travelling. It is very small and light so no need to give up the ritual of massaging your face while not at home.
