This is a knit hat my son used for skiing when he was in kindergarten. It has earflaps and was warm and useful, but he outgrew it after using it a few times. I'm offering it to someone who needs it. Regarding the size, the tag says 48cm-50cm. I've included photos of the hat laid flat with a measuring tape for your reference. Please check the photos for the condition of the item. If you have any questions, please ask in the comments. Shipping will be via anonymous Mercari delivery. Please understand that I will pack the item compactly for shipping. Returns are not accepted for reasons other than seller error, such as "it was different from what I expected." Please examine the photos carefully, and if you are looking for a perfect item, please refrain from purchasing. If you have any questions, please ask in the comments. I do not smoke. I do not have any pets, such as dogs or cats. You can purchase without prior notice. I may end the listing suddenly, so you might think, "This is the only chance to buy it!"
