This is a convenient set of two waterproof mattress pads, perfect for swapping out when washing. I've been using them for about four months, but I always put a gauze blanket or bath towel on top, so they don't seem to have any noticeable stains. They're waterproof, so you can rest assured about milk spit-up and diaper changes. Please understand that these are used items and have been stored at home. Please purchase if you are okay with this. Also, they will be shipped in simple packaging. Thank you for your understanding.
