Doctor Recommended! 2.8X / 7D Eschenbach LED Stand illuminated magnifier. The Scribolux is portable and operates with SMD-LED illumination that provides vivid lighting and never needs replacement! All of these features make writing checks, letters, cards, and reading easier than ever! The functional design is complemented by a large 100mm x 75mm lens that provides 2.8X / 7D magnification.
