I'm selling this because it didn't fit my child and I haven't used it. It's new and unused, but I took it out of the bag to try it on. It's a super cute bunny design. Retail price: ¥1,380 (tax included) I am not considering lowering the price. ↓ Quoted from the website ↓ Colulu Baby Helmet - Prevents falls and head bumps for babies aged 1 year old.
