Wonderful for massage and applying serum
A facial technician used this on my face during a Red Door facial.  I loved it, so I bought one.  I like the smooth side and use it to apply serum.  Coolness of jade feels great when massaging hot face in summer or when my sinuses hurt.  Not too excited about the knobby roller, but it is probably stimulating if you like texture more than smooth.  I bought another one that was smooth on both rollers.  Nice, unique gift to give to girlfriends.
