This is a medical wig from Artnature. I am open to price negotiations, so please let me know in the comments. It was custom-made and cost around 720,000 yen. I only tried it on at home and never wore it outside. I had alopecia areata and lost hair from the crown of my head, so I had a half wig custom-made. It's more like an 80% wig rather than a half wig. You wear it by showing your own hair at the sideburns and nape of the neck, so it looks natural. I've included a photo of me wearing it in the last picture for reference. I think it can be used by boys and girls aged around 8 to 15. Of course, adults can also use it if they have a smaller head size. Head circumference: 54 cm It's made of 100% human hair, natural black, and has a natural hair flow, not straight. It's very high quality and natural, so I hope someone can use it. Thank you very much.
