This is a Petit Bateau hat. I used to put it on my child around the age of 2, but it no longer fits, so I'm giving it away. There is yellowing on the inside (see photo 5). On the surface, there is slight yellowing along the seams if you look closely (see photo 6). There is stickiness where the name tag was, as I had put a name sticker there. Please be aware of this.
