I took the time to match all the pieces to the rikscubes problems and came up with a bunch (around 30) additional 3X3X3 cube problems that can be solved with the given pieces. This essentially doubles the play of the set.
Comes with 17 exotic woods:
Jatoba (Cage), Mahogany (Jig), Butternut/ Jatoba (Box), Padauk, Maple, Granadillo, Wenge, Purpleheart, Bubinga, Leopardwood, Bocote, Chakta Viga, Holly, Schedua, Cherry, Black Limba, and Goncalo Alves (Pieces)
From Cubic Dissection:
The puzzle is a set similar to the Penultimate Burr with multiple problems to be solved. The set consists of a 4×4×4 cage with a 2×2 opening on each face and 14 non-planar penta/tetracubes. The objective is to fill the cage with four of the pentacubes and three tetracubes to complete a 4×4 cube. A jig is provided for testing possible solutions outside the cage, as well as a box which doubles as a display plinth for the solved puzzle. This is a difficult puzzle, with two assemblies having a unique sixteen move solution!
Wait for final invoice for shipping cost.
