Set of 6 bibs I used these not for drool, but because my baby often spit up milk. They can be used on both sides, but all 6 bibs have some yellowing and stains on the white side. The other side is in good condition, I think. I haven't inspected them closely, but I didn't find any fraying. They have cute patterns, so although they show signs of use, they are still usable. I'd like to offer them at a lower price accordingly.
