These are real wings from the Madagascar Sunset Moth. Wings are collected after the butterfly naturally passes.
They are laminated, so they are very lightweight and you can see both sides of the wings.
There are multiple pairs available, the photos show subtle size difference you may recieve.
The hooks are Niobium which is safe for metal sensitivities and come with clear backings and the branded backing card as shown in the photo.
For size reference - the entire length of the backing card is 3.5 inches.
