Cute decoration, not a great hair brush. [SEP] My 9 yr old loves mermaids so I got her this, and she loves it but she can't brush her hair with it. This might be a good brush for a mermaid Barbie, but for any kid older than about a year old it's not going to be a great hairbrush. The bristles are very thin. My 7 year old can't use it either and her hair is thin. It's just a decoration and/or a doll brush. Cute though.
