You send 10 mint stamps

Members exchange lots of 10 different mint stamps in good condition by mail, with a randomly assigned recipient and an exchange ID included in the envelope. After the lot is registered as received, the sender can receive 10 mint stamps from another collector. Each exchange offers a chance to discover new stamp issues from other countries.
