I wish I know the maker of this thing, as I think it's very cool, and feels kind of iconic--or should be! It evades being photographed well, but it's comprised of four parts, with magnets on each interior facet, which fit together in one particular way (the magnets repel each other otherwise.) Fitted together, it makes a satisfying solid, a perfect desk object with a surprise. It definitely has some age, and a nice weight and feel in the hand.

Very good condition, with a little wear around the edges. 3 1/2" x 3 1/2" x 2 1/2".
