This is a Mikihouse Double B cap-style baby hat. The size is 46cm. The size can be adjusted with the Velcro strap at the back. My son wore this. At first glance, there don't seem to be any noticeable large stains, but I apologize if I missed any. There is some fading and wear from use and washing. It has a used feel. Please understand that this is a used item before purchasing.
