I'm selling this because my child has outgrown it. I bought it new in the winter of 2025. It's a Korean no-brand item! My baby has a large head, but it fit perfectly when they were around one year old (10 months to 1 year 3 months). The size can be adjusted with the Velcro strap at the back! There are no particularly noticeable stains, but please understand that it has been handled by someone else, so only purchase if you are okay with that! Please feel free to comment if you have any questions (^^)
