The Triangle 3 is another packing puzzle brought to you by PELIKAN. A 3x3x3 cube shape is required but this time only a small triangular face needs to be filled diagonally opposite each other in the frame. The pieces of this design by Osanori Yamamoto were generally smaller and there are 2 triangular openings on either side of the box. With some clever planning you can figure out the 'out of the box' assembly, and then you will find that a rotational move is needed. That part of the solution is VERY clever – the last part of the assembly can be done just by rotating the puzzle in your hands and allowing gravity to move the pieces into place. This puzzle was crafted in Europe with absolutely fantastic quality. Each of the puzzles of Pelikan design are unparalleled in their class! Every piece of the puzzle is precisely cut and very well made; you cannot find its equal anywhere else.The diversity in wood makes each puzzle a unique masterpiece.
