ORGANIZERS Alvin Spin-O-Tray is the "not-so-lazy-susan" featuring 80% more compartment space. This rotating desktop receptacle is the ideal way to organize artist's and craftsman's tools. Holds pencils, pens, brushes, erasers, clips and even oversized design markers. Rotates smoothly and quietly on its improved 10-1/2" diameter base and the new design offers one additional storage level and seven mini-trays instead of six.
