1. Use nails or coins: at the edge of the iron box or the joint between the lid and the box, gently pull with nails or coins to try to bounce the lid off the box. This method requires some strength and patience.
2. Gently unscrew: Some Disney juice candy tin boxes have spiral lids. You can try to unscrew the lid gently with your fingers. When twisting, you can tentatively turn clockwise or counterclockwise until you find the right direction.
