Angle60 cardcase / card Case

Background: Normally, It is not easy to pick up a business card from the card case, Since the
card is Very thin and the upper and the lower card are very easy to stick together. So how to
solve this problem?
Concept: Unlike ordinary card case, Angle60 is not vertical. There is a 60 degree Angle on
the side, which makes the cards in the case not stay together. Users could pick up only one
card from the case more easily. It would make our life more efficient and convenient.
