Ordinary card sets, are simple flat rectangular boxes, when you use it, you will find that it`s not easy to insert or pull out the card from a card set. So, we cut a corner at the top and cut an arc-shaped notch at the bottom. This design makes it easy to insert or pull out the card. Very simple way to solve problem.
