Review on 🧩 White Mountain Puzzles Puzzle Mystery Box by Alejandro Lane

Works great. The only thing I did to improve them was cut out a piece of plastic canvas to fit the bottom of each so the completed puzzle pieces could be easily removed and added to the main puzzle when completed. The way they fold into each other is very convenient to access and save space. The fact that they are different colors is also a good thing as it helps you determine which pieces go in which compartment. The largest one works like a lid when you're not using it for sorting.
