I wanted to buy something for my niece and thought this penny to dime trick would be great since it came with all of the necessary items (Pen with magnet, Penny shell and mini penny) and all you need to supply is the dime!
Upon receiving this item...the only positive thing I can say about it is that the magnetic pen works. Everything else is way below standard. The penny shell isn't really a "shell". It appears to be stamped metal with the back of a penny embossed on the top. There are no "edges" meaning the sides curl around the bottom, which makes it impossible to place a dime inside...I tried! The mini penny was not stamped properly either with the one I received.
Overall, I feel that this product is a waste of money due to the inferior materials and the fact that you can't even perform the penny to dime trick with it! i'd say save your money.
