The magician places a solid nail inside a rubber tube, and as he holds it the nail starts bending up to assuming the shape of a V. Then the nail re-straightens. Spectators won t believe their own eyes!• Easy to do. The gimmick is completely mechanic.• Well made in stainless steel. The nail is cm 11,5 long (in. 4,5).The nail is cleverly gimmicked and can be examined by anyone. However, we also supply you with another identical stainless steel nail, but totally regular, which we realized on purpose.
