Less allergies - Less contamination risk - More safety


For nurseries, kindergartens but also at home, the GUNMA ball is  the toy which increases the safety and limits the contagion risk among toddlers.


Dedicated to toddlers, the self-cleaning ball GUNMA is made of an innovative photocatalytic material which permanently cleans the ball surface.


90% of bacteria disappeared with natural or artificial light according to JIS R1702  - Test method for antibacterial activity of photocatalytic materials and efficacy.


Mouth diseases transmission risk as any kind of contagion are reduced almost to zero when using the GUNMA balls.


Colorful, soft, bouncing like a traditional ball, the ball GUNMA is used like any ball while decreasing the risks of contagion and allergy.


With an integrated internal inflation valve, the pressure of the ball is adjustable so that it has a low rebound and is soft for indoor use or higher rebound for outdoor or ball pool if more air pressure in the ball.

    About GUNMA ball:

    GUNMA has been developped in Japan by a scientist and engineer team

    Manufactured according to European and Japanese safety regulations, this self-cleaning ball GUNMA contains no phenol, no cadmium, no phtalats according to European Directives and also has no poisonous material as per the Japanese Food Safety Law (JFSL) and ST safety standards.


    What is photocatalysis?


    The application of photocatalysis was discovered in Japan by Professor Akira Fujishima at the University of Science in Tokyo in 1967 and of which he is the current president.


    It is naturally in Japan that the first industrial implementations using the process were developed in the 1990s.


    Photocatalysis activates an element called semiconductor using light energy and using the natural humidity of the ambient air in order to facilitate the reaction.
