Grading Check Cards There are 10 cards each for A, B, and C, for a total of 30 cards. The size of the picture part 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 other event after using it for grading. We can adjust the number of cards for ±80 yen per card. If you would like to change the number, please consult in the comments section. These are handmade items. Please be aware of this. Please refrain from price negotiations.
