Product Name :

Minus-Ion Magnet

Introduction of Material :

With more than 2 years of researching and developing, we finally got the the patent of Minus Ion Magnet for 20 years from government. The main material of this product is ferrite powder, which compound with purity minus-ion powder, and finish with a complex processing of manufacturing. The surface's magnetic strength is around 100 ~ 1000 Gauss. We have exported the same one to Japan for making health products since invented, and we believe that this products would be used on magnetic health product in the fuutre, not only in Taiwan, but also in worldwide. At the moment, we use this products in our own products like support belt, insoles and sports wrap set, etc.
