Query: Bad

The slider on the cards, most of them do not work. The come out when you try to slide. They go in crooked. The slots are uneven. This is a waste of money, these cards. There is nowhere on the box about the size of the balls if you need to replace them. Not worth the nearly $40.00 that I paid for this product. Cheaply made. Over priced. Would not recommend to anyone.
