Very tiny 4mm (.15 inches) clear point back glass rhinestone earrings on clear acrylic clip on backs for non-pierced ears. This size is appropriate for teens or those who prefer a dainty earring style. The clear acrylic clip on style is light and gentle for ears. 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.
