Good for office cubicles and work benches, this portable mirror has a clamp for mounting to any edge up to 2 3/4" thick. Use the flexible arm to position it however you need. This mirror has a lightweight acrylic surface that resists breakage and will split into a few large pieces rather than small, sharp shards if shattered upon impact. It is convex to provide a wide field of view for seeing around corners, down aisles, and over counters.
