Eco Box by Mark Southworth
There are various card boxes on the market. For example 3sixty by Wayne Dobson, Clarity Box by David Regal, or the classic wooden card box.
Marc Southworth has now created a very inconspicuous, small, black box that fits in every pocket.
A spectator draws a card and signs it. You make the card disappear from the game and in the box the card appears, folded.
You take the card out of the box, unfold it and it's the signed card.
The principle of the box is the same as in other versions. But this box is really unsuspicious and handy.
You will receive the handmade box (approx. 4x6cm) and an English video link with the explanation.
