Framed Chaos, by Lucie Pauwels

This is a Packing Puzzle slightly different than usual. You have four pieces to fit into a frame, but this time the frame is "undefined"!
It's made up of two parts that can obviously be flipped and rotated, thus generating quite a few possible combinations! 
To avoid spoilers, in the last photo the lines dividing the pieces have been deleted...

Dimensions: 60 x 60 x 20 mm.

I ship from Italy all over the World. You will choose the courier / shipping methods and you are responsible for custom duties.  For any questions and to allow me to check the shipping costs for you, please ask before bidding.
