The puzzle consists of ten flat pieces. There are five notches, each of which can either be tall or short. Each piece has a different combination of notches. They can be arranged as shown above to create a cube.
This puzzle was designed and made by Jean-Claude Constantin and was Luc De Smet's exchange puzzle at IPP28 in Prague. It is nicely laser cut with what appears to be a veneer of some sort, which gives it a pretty good finish for a laser cut puzzle.
