I recently purchased this, but it doesn't match my hair color, so I'm selling it. I took it out of the bag once to check the color, but immediately put it back in. I have not tried it on or used it at all. The length is 26 inches (approximately 66cm), as stated. Instant purchase is OK. This was introduced by YouTuber Cosme Wota Channel Sara. For reference on how to use it, I recommend her short video.
