I purchased these earrings years ago from a select shop. The motif is likely silver, and the posts are probably titanium (though I'm not certain... I've forgotten). Size: Approximately 12mm x 8mm The wings stand up, giving them a three-dimensional and eye-catching look! It's a unique design, so how about it if you want to stand out? Please refrain from purchasing if you are concerned about allergies, as I am not certain of the materials. I will carefully package them to prevent the posts from bending during shipping! Thank you.
