The Magneticard is a single Blue-back Bicycle card with a petite, potent magnet buried within it. The neodymium disc magnet is 10mm (3/8”) in diameter and a mere .4mm (1/64”) thick.
The magnetic is sandwiched between a one-layer face and a one-layer back, which are fused together with two layers of dry mount tissue. The resultant Magneticard has the stiffness and snap of a regular card. It will pick up and hold a magnetic or steel core quarter, or any small, shimmed object.
Court cards are used for additional camouflage.
"I don't know what first attracted me to Tom's Magneticard - it may have been the metal fillings in my teeth. But whatever it was, I'm now an enthusiast! Caveat: Keep the card away from your mouth."
