Patch magnets have a self-adhesive backing that attaches to the back of your promotional product to give it magnetic properties. They convert your design into something similar to the ubiquitous Fridge Magnet and are used to magnetically attach and display printed material that is often used to promote tradespeople, local eateries retail stores and other professions or service providers. The adhesive-backed, flexible magnets are designed to hold lightweight material such as calendars, invitations, menus and the like, so contact information for services is easy to find and close at hand when the occasion or need arises. The low strength flexible magnetic material in these patches makes them very economical and suited to large production runs of advertising material that is often distributed in suburban letterbox drops.

The patches are sold in units of 1000 pieces for this reason and bulk purchases are even more economical. Patches that are thinner than this 0.8mm product are also cheaper and suitable for very lightweight advertising material. Although the magnetic patches are low in strength,applying more than one patch magnet on the back of a heavier item will provide considerably more holding ability. A patch on the back of each corner of a plastic or cardboard sign for instance, will allow it to be attached to any metal surface. Self-adhesive magnets are super convenient because they transform non-magnetic products into magnetically compatible ones. Some handy types and hobbyists find these magnets help in their creative projects, as do art and craft enthusiasts.
