Human Hair Colored Clip-In Extensions (18 Inch) Mary Averost07/27/2015 at 5:22 pm 5 out of 5 So Much Fun! We purchased these fun colored clip-ins for my daughters birthday party. She invited about 20 of her girlfriends over for her 10th birthday, and the hair was definitely a hit. It was a lot of fun to see them pick their favorite colors and put them in each others hair. I would highly recommend them to anyone with young girls at home.
