To use, simply place the stone ice cubes in the freezer for approximately one hour before use. For a normal glass, two or three Nordic Rocks will be fine. They give off their cold gradually and equally.
For maintenance, rinse your stones under clean water and store them in the leather pouch provided. They are then ready to serve you again any time to your fullest satisfaction.
Nordic Rock - no better way of cooling your drink.
Comes as a set of 10 complete with leather storage pouch.
