• 13/16" diameter x 5/64" thick.

• White painted to provide a discreet professional finish.

If you are looking to use a magnet then you need a steel surface, or another magnet, to attract to. A magnet will attract to a steel surface in direct contact with equal strength as a magnet to magnet arrangement, therefore, self-adhesive steel discs can sometimes provide a more cost-effective solution. However, it is important to remember that if there is a gap between the two, then a magnet to magnet attraction will be stronger.

These small white painted steel discs are supplied with convenient, strong 3M™self-adhesive on one side which means they can be stuck to almost any hard, flat surface to create a magnetic surface. They are an essential part of any crafting tool kit and are often used by galleries to hang artwork.

Each sheet has a striped north-south polarity on the magnetic face to give a secure grip. To ensure that the grip remains secure, we recommend allowing between 24 to 32 hours for the adhesive to cure.
