Kimetsu no Yaiba Kocho Shinobu Cosplay Wig The wig is styled to look like a Yawa-maki (formal updo) using wig spray and glue, so the back will not come undone. This was made for practice and is unused, but please refrain from purchasing if you are concerned, as it is a self-made set. It will be shipped via Takkyubin Compact. There is a possibility of it coming undone during shipping. I am also accepting orders on the wig order page.
