Hakuzo Waterproof Sheets, Set of 3 Since this is a hygiene product and unopened, I haven't been able to measure the size, but they were used on a single-size care bed. Use them for various purposes, from small children to the elderly, such as "bedwetting対策," "food spill対策," and "pet urine対策." They are widely used in childcare, nursing care, and are very convenient. Please refrain from purchasing if you are overly concerned about details.
