One of our customers found these for us and were we ever delighted! Such lovely angel wings, butterfly wings, fairy wings, .... These are made of hard plastic and are from the mid-20th century! We just love them because you can use them either way (as shown in the illustration).
Each has a textured, embossed side and a flat side, so they can be glued as well as used as charms!
You can paint them, rub them with pigments - there are just so many possibilities.
Each wing measures 1-3/4 inch across by 1 inch high.
