This item was included in an obstetrics set, but was not used. It appears to be a disposable sheet for childbirth, but since it is unopened, I have not been able to confirm the contents. As it is specified for use during labor, the structure may be different from a general bedwetting sheet. Photos 4 and 5 are quotes from the manufacturer's website. The expiration date is September 2025. The shipping method may be changed. It has been stored at home for about 5 years. Please consider this with understanding. - Brand: Osaki - Model: P100120-GS Pink - Expiration Date: September 2025 - Quantity: 1 sheet
