Checkout Packing Problem Wooden Puzzle

The wooden box holds 6 different wooden shape pieces, with different wood colors.

The objective is to take all the pieces out of the box, mix them, and then try to put them all back inside the wooden box.

It seems that the 6 pieces will never fit back into the box. Most of the times, you will end up with one piece outside of the box, but you know it can be done!

Can you solve the problem?
