This listing is for a mirror image pair of Butterfly vinyl decals which measure approximately 3 inches tall and 3 inches wide. These are not window clings. They are made from durable (6 year) indoor/outdoor vinyl and will stick to any smooth surface. The decals come in three parts: the backing, the actual decals themselves and the application tape and are ready to apply when you receive them. The pictured decals are shown in black but the ones you will receive are white. I will also include detailed application instructions with the decals.
