These sweet blue bird earrings are made using 100% recycled acrylic. The quality is just a great as virgin acrylic but a lot better for the environment. I have made these using surgical steel ear wires which are good for sensitive ears and the stoppers on the back are latex free. They are 4cm at the widest / longest point, not inc the hook. These are made with permission using digital artwork from http://mycutelobsterdesigns.etsy.com
