Our post stud crown pink LED earrings glow brightly when activated. They are constructed of stainless steel for quality and durability. They run on replaceable LR521 batteries and will provide around 40 hours of use. Friction backed attachments ensure they stay on snugly and securely so you will never need to worry about them falling out. Our LED earrings are a great low cost solution for your next glow party or special event. The bright LED lights will not only enhance your outfit, but make you the light of the party! We offer a total 9 different colors of this beauty in the DirectGlow storefront (Multicolor, Blue, Green, Yellow, Orange, Pink, Red, Purple, White)! We also sell flower, star, and heart LED earrings with the same color choices. PLEASE NOTE THESE EARRINGS ARE NOT FOR CHILDREN UNDER 3 YEARS OLD!
