Four words characterize this product: Okito, Boston, Bloc, Duvivier.
Okito: The Okito Box is one of the great classics of magic coins. With the Duvivier Coin Box you can perform all routine and passes of the Okito Box: Travel and transpositions of parts, crossing the box or hand, processing of parts, etc..
Boston: The Boston Box is the box rigged complementary to the Okito Box. It can perform the same types of effects with the basic box, but with a little extra that makes your performance even clearer and more inexplicable.
Block: is the icing on the cake of box routine parts. The block can finish the routine on a breathtaking climax: the box becomes a solid block, which shows the impossibility of what the public comes to see!
Duvivier: In principle, the combination of these three boxes is restricted to parts specialists because it is particularly run multiple exchange box. The Duvivier Coin Box is a revolution in the magic of the parts, because it allows you to merge the three principles into one. Yes, you read that right, THREE BOXES: Okito, Boston, Bloc. No exchange box. Everything is given for examination before, during and after!
