Grading Check Cards There are 15 cards each for A and B, for a total of 30 cards. The size of the image area is 10.8cm (height) x 8.8cm (width). The design is the same on both sides. Each card contains a bingo card, so you can enjoy it as a bingo game at a second party or similar event after using it for the grading check. We can adjust the number of cards for ±80 yen per card.
