Arrived promptly and safely. An interesting wooden puzzle of 4 wooden blocks with embedded vertical grooves (to represent "sticks") of the same lengths. When arranged in certain ways, the 4 blocks will display a different number of grooves. I am a big fan of these types of optical illusions. This is a high-quality item that I am proud to own. And I am eager to show this off to friends, co-workers, etc.
