Vault (Gimmick and Online Instructions) by Leo Smetsers - Trick
Leo's Vault is a precision made, up to date version of Jack Lippincott's classic Lippincott box. This beautifully engineered aluminum box has a really nice weight to it. It is strong, sturdy and the best part is it can be handled by the spectator with no chance of them finding its clever secret.
For you table hoppers out there, the Vault can be reset in front of your spectators (so no more hiding in a corner to reset).
The Vault comes with everything you need to perform it and an instructional streaming video.
