Tinacious by Scott Alexander

TINacious is a specially gimmicked mint tin that has no flaps or magnets. Designed by Scott Alexander, this highly durable gimmick allows you to secretly load a signed playing card into a mint tin right under the audience’s nose. The best part is that when the mint tin is opened the card inside is actually their card. The audience can remove the card from the tin themselves. There is no switch to catch because no switch occurs.
