Pony extension, straight, gray, long, 55cm. The color is as shown in the photo (although it's gray, it's a color close to silver). It's not a clip-on type, but a type that you attach by tying with a ribbon. I bought it planning to use it for graduation, but I'm selling it because I wanted it to be a little longer. It's new and unused, but it has been stored at home, so please purchase it if you don't mind that.
