Rubber Coated Magnets
Magnets coated with premium rubber are ideal for use with fragile or easily marked surfaces such as furniture or displays.
The premium black rubber finish looks classy and discreet in any environment. What’s more, the rubber coating increases friction between the magnet and the surface it is attracting, making it less likely to slide down a vertical surface compared to a non-coated magnet.
