Purchased new on 7/25 (Friday) Unopened This item has not been opened. I have not touched the contents. Mesh Cap Hat Black Since it's all mesh, it doesn't get stuffy, creating a good environment for the scalp. I took the photos while it was still in the outer plastic. Men's size M to L I have opened another one and measured it with a measuring tape. I have uploaded photos to the other one, so please check them. Size adjustment function It's rubber, so it stretches a little. About standard size The size is shown in the photos. Please look carefully and confirm before purchasing! Photos from the 7th onward are of a hat that was tried on once and sold previously. This product is unopened, so please rest assured. If you have a request after purchase, I will open it to check if there are any problems before packing and shipping. We offer no guarantees. Also, it is listed elsewhere, so please check if it is in stock before pressing the purchase button! I am not accepting price offers. To make it thinner, it will be flattened as much as possible, and the part that covers the head may wrinkle, but it should return to its shape while you wear it. I think you can wash it in a laundry net. I will stop listing it at the end of August!
