This is a Miki House hat for use in the pool. It also prevents sunburn on the neck. It's made of stretchy material and is free size. It depends on the head size, but I think it's suitable for children from around 2 years old to around the age of a senior kindergartener. It's still usable and I personally think it's in good condition, but there are some areas with what look like lint, so please check the images. Therefore, I'm selling it at a low price. I'm sorry, but I can't offer a discount because it's already priced low. I'm decluttering. I'd like to pass it on to someone. I'm asking that only those who don't mind the small details purchase it.
