12mm x 10mm (.47" x .39") ladybug earrings on invisible clip on style backs for non-pierced ears. The ladybugs are made of acrylic with plastic backs and rubber stoppers making a 100% metal free earring. The clear plastic clip on style is light, gentle and are hypoallergenic. They slip over and hug the earlobe and many say they can't even feel that they are wearing earrings unlike most metal style clip on earrings that pinch and feel heavy.
