Rattle Box (Coins) by Jose Arcario
An original T. Nelson Downs gimmick, later improved by David Roth, and now made with the best tools and materials available.
With this gimmick you can simulate the sound of coins colliding in your hand when it is actually empty. The sound achieved is better than any other system on the market because there really are coins clinking together.
The gimmick can be used with any coins up to half dollar size. Coins not included.
