Glow-in-the-dark cards

Glow-in-the-dark cards show their image in the darkness. It's enough to recharge them under a common lamp (whatever type) for a few seconds and they begin to glow. This special silkscreen ink is not radioactive, so the product is absolutely safe. Our technique uses a special white powder so that usual greeny colour is avoided, so it glows white. As an alternative, standard green ink can be used.
