Used for one month when my child was in their final year of preschool. I bought it because it was required at the new preschool after we moved, but my child was already not napping by the time they were in their final year, so it was used for less than a month. Also, I purchased it directly from a private preschool, so I no longer have the receipt, and I don't know the details, but I believe it's 100% cotton. It has rubber bands on all four corners. A name sticker was attached to the edge. Size: Approximately 58cm wide x 130cm long. ■About Packaging It will be put in a plastic bag and compressed for packaging. #Naptime #Cot #Cover #FittedSheetCover #Preschool
