These are on Close-out at a highly reduced price because they have a very slight yellow sheen to the plastic. It does not impact performance at all and most won’t notice but we do want to acknowledge the fact.
The magician places a deck of cards and a plastic case on the table. He takes a card out of the deck and shows it to the audience, asking them remember it. He then returns it to the deck and puts the entire deck into the plastic case. After a magic snap the magician throws the case into the air and the deck of cards vanishes from the case, leaving only the previously shown single card.
This is a miniature deck made to resemble the bicycle Mini Decks. Durable construction!
