Purchased from Seiwa's package link. This item is already discontinued by Seiwa. I have stored it for about 2 years, but the contents are still in good condition. Size: Width 16.5cm, Height 11.5cm, Lid 5cm *Measurements are approximate, so there may be a difference of about 1mm. I purchased 50 sheets for 2,350 yen. This is a partial sale of the remaining sheets after opening the package, and I can only set the price from 300 yen, so I've set it to 300 yen. There are also 250 unopened sheets, and I will offer a discount if you purchase a larger quantity, so please leave a comment. 50 sheets: 1800 yen 100 sheets: 3300 yen 150 sheets: 4500 yen 200 sheets: 5500 yen 250 sheets: 6200 yen
