Magnetic Business Cards! Unlike regular business cards, Magnetic Business Cards are here to stay. When you receive a business card, you have to weigh up whether it is worth the space in your wallet and if it is not, it goes straight into the bin. On the other hand, Magnetic Business Cards are useful to the recipient, allowing them to hold important notes, bills or photos to their fridge or filing cabinet in the places that matter most - in the home and in the workplace. These magnets are produced with commercial grade 0.4mm magnet material to ensure longevity of the product, and has a finished thickness of 0.6mm. Each magnet is finished with a Gloss Celloglaze which is extremely popular.
