Trading card sleeve

Abstract

This item is a trading card sleeve. It is a trapezoidal sleeve for use on a card sleeve that completely protects the card. The usage method is to insert the card from the lower right diagonally to the lower left diagonally. To completely protect the card with a card sleeve, previously two rectangular card sleeves were used, but this time it is one rectangular and one trapezoidal. Advantages of the trapezoid: 〔▲1▼Cost cut〕The area is smaller compared to a rectangle. 〔▲2▼(The top and bottom of the card sleeve are easily distinguishable) When the card sleeve spills, it is not easy to tell which is the top and which is the bottom and one has to check the card insertion opening each time. In the case of a trapezoid, it can be immediately recognized. 〔▲3▼(It is fast to insert the card into the card sleeve) In the case of a rectangle, the card is inserted from the bottom into the card sleeve. When the upper part is 66 mm wide and 91 mm long, the card insertion opening is 66 mm. In the case of a trapezoid, it is inserted from the lower right diagonally to the lower left diagonally, and depending on the diagonal angle, it can be more than 70 mm. Since the card head can easily enter compared to a rectangle, it is faster to insert the card into the card sleeve.
