Real butterfly wings are used after their natural passing and turned into wearable art! Nothing is done to harm the butterfly. They come from butterfly preservation farms worldwide. Each wing is carefully laminated and cut bordering its elegant curves then attached to hypoallergenic earrings with earring backs. These wings are from the Graphium Weiskei butterfly and measures approximately 1"x1" each. They are a great pair of smaller earrings which will come with an info card to learn more about the butterfly. Jewelry is shipped in a usps padded envelope and takes 3 to 5 days to reach anywhere in the continental U.S. or 7 to 10 days for any international destination. These always make a good gift for friends!
