These were our kids' favorite drawing "toy". Tracing and out-lining the shapes for hours on end. A favorite for years and years. So much fun for kids of many ages. It's also a puzzle; the shapes fit in and out of the trays; there are 3 trays with 6 shapes in each tray. Each tray can be used to trace shapes. It's just a timeless toy. For ages 3 on up.
