Kim offers lots of versatility. These 19" curly extensions / fill in pieces can be used individually to dress up your own ponytail, have a few curls hanging down from an up-do or pulled back look. Add a pop of color with a contracting color. Also, you can use 6-8 of them to create a fuller longer look all over. Individual pieces are perfect for adding highlights or low lights or streaks of color. Follow the same steps for attaching as with all extensions.
