I purchased this, but I'm selling it because I ordered the wrong length; I wanted a long one. I haven't used it since opening it. I've been storing it in a bag, so it's a bit messy, but I thought it would be better to pass it on without doing anything to it. It's human hair, so you can dye it and use a curling iron. I've been using this type for a long time and I'm very satisfied with it! The length is 40cm from the crown to the longest part. The color is brown.
