This is a Japanese wig. Unused. The outer size is about 11cm. The inner size is about 9cm. The wig color is black. It makes it easy to style your hair. I think it's convenient when you don't have time. (I think it's also good for Western clothes.) Simply gather your hair in the back with a rubber band, etc., put on the wig, and secure it with pins, and you're almost done. * There are some slightly frayed hairs and visible glue (though I don't think it's noticeable...). There is no special box, but it will be carefully packed and shipped quickly.
