This cube puzzle is the same as Cube Puzzle 1 - Transportation, but has smooth sides so there is no tactile information to help put this puzzle together.  It is made up of 5 pieces and when put together correctly, these pieces form a cube that is 1 3/4" big. Some of the pieces have magnets so when assembled in a certain way, the magnets will hold all the pieces in place, and the cube will not fall apart when picked up. 
 
Note: If you're wanting an especially hard challenge, also order the Cube Puzzle 2 - Challenge puzzle and/or the Cube Puzzle 3 - Challenge puzzle. When multiple cube challenge puzzles are disassembled and the combined pieces mixed together, you will have your work cut out for you in trying to assemble the pieces into separate cubes!
