The Slim Cera, unique object and true beauty accessory, was created by stones and minerals lover, M. Hirotoshi Hattori. 
As the president of a jewelry company, M. Hattori was constantly in contact with stones. Having observed their beneficial effects and with his growing fascination towards them, Mr Hattori investigated further. He invented artificial ceramic by pounding several stones and mixing them together. He then participated in the creation, in particular of the marble pillow ceramic.
The feedback was extremely positive. The results of the ceramic ball, which had the ‘pillows/rollers’, were instantaneous.
Effects such as softer, firmer skin as a result the Slim Cera was created.
