Zollstöcke (or folding rulers) is an attractive packing puzzle by Jean-Claude Constantin. The aim is to fit all four "folding" rulers into the frame. The ruler pieces themselves do not actually fold, making the task of fitting the unwieldy segments into the framed area a daunting task.
This puzzle is actually quite large, measuring in at approximately 30 cm (12 inches) long, making it the perfect size for a coffee table feature attraction. A great puzzle for the wood lover or carpenter.
