Frontier Co.'s [Saratto Waterproof Sheet] * Color: Mint Green * Material: Top: 100% Polyester Bottom: 100% Polyurethane * Size: 150 x 90 cm (Partial Type) This item is from Frontier Co., and as it's a reliable waterproof sheet, it should still be usable. How about using it as a spare when you wash your existing waterproof sheets? There are no noticeable stains, but please refrain from purchasing if you are looking for a perfect item. It has been washed, but there are wrinkles. It seems ironing with a pressing cloth is possible, but as it's made of polyester & polyurethane, I'm a little worried, so I haven't ironed it. I will send it as is, so please consider it if you understand.
