This popular size is now offered with a thermoplastic rubber-like coating. They won't mark or scratch surfaces they come in contact with. The coating helps limit slipping on smooth surfaces.
These magnets are similar to the natural rubber coated magnets we previously offered, but with several improvements. Unlike natural rubber, which can have tiny pin-holes, this coating can seal the magnet from moisture. Our underwater testing is in progress! These magnets are easier to separate. They and are nicer to handle and cleaner than blackened natural rubber.
