I recently purchased this on Mercari, but the color didn't match, so I'm selling it. (I only tried it on once at home.) The following is quoted from the original seller: This item is perfect for 360-degree close contact and adding a little volume with its 3D air structure. Material composition: 100% human hair Size: Length: approx. 30cm, Base size 5x8cm Type: Straight Color: Dark Brown *Because it is 100% real human hair, a few gray hairs may be mixed in. You can remove them if you are concerned. *The hair's initial kinks from opening can be restored to a natural style by lightly wetting it with water and setting it with a hair dryer.
