These stunning Australian Floral magnets come in 12 different designs and make a statement in your kitchen or studio. This set of four is - Set C - while the others can be found in my store. Size: 2.25" or 55mm Internal Magnet: I have placed a strong Neo magnet on the inside of these magnets so no magnet is visible on the outside. These are much stronger than the usual peel N stick magnet normally found on these button magnets which only hold 1-2 pieces of paper. My magnets have been improved to hold 8+ pieces of paper so they are more than just decorative.
