I obtained this concept while vending at a festival from a lady looking for mood earrings for her daughter. Just like the mood rings change color from body temperature. Believed to be able to depict one's mood. These color-changing accessories will have people looking like and some asking you if your earrings just changed colors. Play with them if you like and pretend you don't know what they're talking about with these playful accessories. Earrings measure 10mm attached to a surgical stainless steel post. Unlike the originals, these have a smaller dome. All findings are nickel and lead-free.
