The expanded coin shell is a very useful gimmick. There are infinite effects that can be achieved with it. Its use eliminates many difficult passages and in many cases creates beautiful effects that are not possible even with the most difficult handling. Excellent realization! In the box you will also find the explanation of the beautiful routine, in which a coin pierces a borrowed banknote (it will also require a regular half dollar that can be purchased separately). This expanded shell has the characteristic of being also sensitive to magnets. An extra weapon in the right hands!
