The Muji word cards are likely unused and contain 100 sheets. They were originally sold in a set of 5, but 4 have been used, so only one is being offered for sale. The word cards in the upper right of the photo were probably purchased at a 100-yen shop. As shown in the third image, the inside has a blue 5mm grid. According to the cover, there were originally 80 sheets, but a few have been used, and I just counted about 65 sheets remaining. The bear? word cards are unused. Individual sales are OK, but since the original price was 300 yen, the price will remain 300 yen. Currently, they are scheduled to be listed for sale until the end of January.
