I purchased this adorable hat with a fish design from Ragmart♪ It has an elastic string. It also has a sunshade at the back of the head, which is great for protection from the heat. I will fold it to fit within 3cm for shipping. I wore it for a short time about twice. There are no noticeable damages, but since it has been stored by a private individual, please consider carefully before purchasing if you are concerned about minor details. Thank you very much. m(_ _)m
