I purchased this at Aeon last December. It's a Topvalu disposable waterproof sheet. 【Sheet Size】 Approximately 59cm x 90cm 【Price】877 yen (tax included) There are 3 packs of 10 sheets each. 2 packs are unopened, and 1 pack is unused but opened. I will ship these in the cardboard box as they are. Thank you for your understanding and consideration.
