Mirror, Convex, D:75mm, Fl:200

This is a circular convex mirror with a diameter of 75 mm (3 inches) and a focal length of 200 mm (8 inches). A convex mirror has a reflective surface that curves outward, producing upright images that appear smaller and farther away. This design provides a wide field of view, making the mirror useful for science education, security, and vehicle safety. Each unit is individually packed in a protective paper bag and also available in convenient 10-pack boxes for schools, laboratories, and professional use.
