These color changing stud earrings are so cool! I have a friend who wears them & it is so much fun to see them change color throughout the day! The colors change based on the amount of heat that is present. Cool = Orange Medium = Green/Light Blue Hot = Dark Purple These earrings are made with High Quality Epoxy Resin & Hypoallergenic Plastic Post. If the post are too long, simply snip ends to desired length with a pair of scissors. I love & wear my plastic post stud earrings 24/7. There is no irritation that metal can bring & they are very comfortable to wear. This listing is for one pair of 10mm star stud earrings with a BLACK acrylic border. The video shows the color change with a clear acrylic border. Gift Wrapping available (please see pulldown menu for option) Have a great day! #157 Novelty Earrings/Mood Color Changing Stud Earrings/Chameleon Earrings/Hypoallergenic Earrings For Sensitive Ears/Cool Mood Jewelry
