This sturdy metal box is used to handle the bloc hyalin (which is sold separately).
Le Bloc Hyalin is in its raw state but includes a hand-sanded and rounded end for a smooth application. Wet it under lukewarm water and pass it over the desired areas.
The stone then covers the skin with an invisible layer of thousands of micro-crystals preventing the development of bacteria responsible for bad odors.
Use this metal box to store your Le Bloc Hyalin after every use.
