A very clever mechanism. But it doesn't pull much weight. It has difficulity pulling a selected
card out of a deck, unless you are holding the cards very looseley and wriggling them in your hand
to give lots of air between them. But it is so silent is is amazing. The string is very invisible.
The whole product is good quality. But stick to really light items like sponge balls, single cards,
kleenex, dollar bills. A hint, add a drop of hard glue to the button. It will make it easier to
find in your hands when you are trying to keep the pull hidden. (The button end feels the same as
the other flat end.)
