Unlike many bat decorations, these are made to appear as if roosting. Thus they are "cocooned" in their own wings, hence the name; these wings are also made of a mesh-like material to produce an eerie translucent effect, especially when backlit. To give them a scarier look, they have inset plastic jeweled eyes that can catch the light to make them seem to glow. To display them, a small wire extends between their feet for hanging purposes. They come in two sizes: Large and small.
