These are unique, colorful bibs. The back is made of gauze material. The combination of colors and patterns is cute. The flashiness is the key point. I bought these at a flea market but never used them, so I'm selling them. Recommended for those who need multiple bibs for daycare, or of course, for children who drool a lot. Although they are new and unused, please understand that they have been stored at home and purchase accordingly. Please refrain from purchasing if you are sensitive to this. Season: Spring, Summer, Autumn, Winter
