Super Rubber Magnet with 4 times more adsorption power than conventional product.



	High magnetic force sheet with neodymium of the strong adsorption power, that is 4 times higher in comparison with conventional rubber magnet. The flexibility of the sheet also improves more. With scissors and a cutter, a clipping can be made easily in various form.
	→INQUIRIES

Flexible Magnet Sheet of rare earth Nd-Fe-B.
The Sheet surface does not have the oxidation and falling off of magnet material for a multilayered structure body.
In comparison with normal rubber magnet, there is about 4 times adsorption power.
This product is superior to conventional rubber magnet in flexibility, the reconstruction characteristics and can easily clip it out in scissors and cutter.
