This is a hardwood pentominoes set in wood box with cover. It sits in the box 2 layers deep. The size large box is about 4.7" X 4"x 1.6" deep. Based on your requests, We have made this 3D set with the width of the pieces equal to the depth. This gives the ability to make the 3 dimensional puzzles that are offered on some of the websites that specialize in pentominoes (which we provide with your instruction sheet) in addition to all the other flat Pentominoe shapes.
Level of Difficulty: Level 3
