Potterybarn Kids! Perfect for nursery, little girls room or general home wall art if you ❤️ 🦋! Butterflies have a 3D effect as wings span out off of wall. Beautiful mirrored design but are super lightweight material not actual mirror. Several adhesive pieces left in bag with original description card but could use whatever you choose to adhere to wall. These were recently taken off of my child’s wall so small piece of adhesive on back may still remain. Easy on/off application on wall. See pics for details. Please let me know if any other questions! Non smoking home.
