The wings use aurora powder. The color changes depending on the angle. The trading card case size is B8. While I have made sure the parts won't come off, please handle the product with care as it has protruding parts. This is a handmade item by an amateur. Please forgive any glue marks, etc. I hope you enjoy it as a unique handmade design. ↓ Motifs, parts, and colors used: Ribbon (purple, pink) Black Lace Frills Hearts Wings
