This is a waterproof sheet purchased from Nishimatsuya about 10 years ago. It's sized for a mini baby bed, approximately 60-90cm. There is one stain, about 2cm in size. See image 5. The elastic on the corners is stretched out. The waterproof backing is wrinkled from washing. There are no holes, and I believe the waterproof function is still effective.
