Lifekind certified organic flannel mattress cover, crib size. Use as a layer under your baby's sheets to protect mattress. Standard crib size and fitted to stay securely on mattress. I see some minor spots, please see last listing photo. They're very, very faint. A good day in sunshine outside might remove them. This is mine, bought new. It has been lovingly cared for and I don't use any scented or dyed laundry products. This mattress cover is in very, very good condition and is ready for a new baby. I also have crib-sized bedding, all organic, for sale.
