Capture the magic of real butterfly wings in these unique and functional post earrings. Real butterfly wings are acquired from preservation farms after their natural passing and information cards are included to learn more. These butterfly wings are lovingly preserved by Asana Natural Arts in Salt Lake, Utah. The artists secure the wings inside these 1/2" (12mm) silver-plated post earrings. The wings are sealed with resin making them waterproof. Regular earring backs are included or you can upgrade to have 1.5" silver threaded dangles which provide another level of elegance.
