You know, those 15 squares in a 16-slot frame, where you slide them around to put them in the right order. They usually have numbers or a picture on them, but these are blank white squares so you can write, draw, or paste you own puzzle on them. Each is 2-3/8" square. The monitor puzzle is set in a computer-monitor-shaped back; the bulb puzzle in a hand-friendly lightbulb-shaped back.
