Handy pocket magnifying lens no bigger than a credit card, with a window-style fresnel lens measuring 77 x 26mm, 3x magnification. Larger surrounding finger grip area with smart blue and white printed design. Protective film sleeve included. Great lens to carry in wallet, pocket or purse, for checking food labels, instructions, smallprint and imagery on packaging, menus, timetables and all those other things where the makers forget not everyone's eyes are as young as they once were.
