SMB888PC-BLK Rubber Coated Magnets - Stanford Magnets

SMB888PC-BLK Rubber Coated Magnets

These cubes are coated with a durable layer of plastic.  They won’t mark or scratch surfaces they come in contact with. They are also completely weatherproof.

The SMB888PC-BLK blocks are a great option for heavy holding on magnetic bulletin boards, and are perfect for heavy holding outdoors.  They are great magnets for demonstrating magnetism as they can be slammed together many times without damage. Please note: Slight color variation may occur from order to order.
