Coinvelope by Alexander de Cova (Strongly recommend)

"This is new to me. I have not seen anything like it. Your touches make it a miracle vanish. Very clean - very natural. Excellent." - Michael Close

"What a brilliantly simple, devious and clever idea! It is so deceptive, I love it!" - Nick Einhorn

Coinvelope is Alexander de Cova's latest creation. With this super simple (and therefore reliable) gimmick envelope you can vanish a borrowed, marked coin and have it reappear anywhere. The vanish is absolutely convincing and easy to do. The diabolical envelope does most of the work.
The envelope can be constructed literally within seconds, without using any glue or special supplies, as Alexander shows on the video. Can be used for close-up, strolling or parlour and even stage. Even (wedding style) finger rings can vanish with this multi-purpose envelope.
