Kimetsu no Yaiba Kochou Shinobu Cosplay Wig The wig is styled to look like a Yae-maki (Japanese updo) using wig spray and glue, so the back will not come undone. This was made for practice, so it 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 also accept orders on my wig order page.
