4L Puzzle by Yasuhiro Hashimoto

The goal of the 4L Puzzle is to fit the 4 L-shaped pieces inside the restricted box. How hard can it be?  

Well - it's much harder than it looks. Putting three pieces inside is easy, but most people will struggle for HOURS to fit the 4th piece...

...That is, if they ever do.

The 4L puzzle was awarded a honorable mention in the 2015 International Puzzle Party for its ingenius design.

Arrives in a plastic travel bag.
