Magnify stuff with this 2" x 1-3/4" acrylic Fresnel and light it up with the little white LED light on a pivot. Both are in a 3" x 1-7/8" frame, along with a pair of AG-10 batteries that you could replace if you have a tiny Phillips screwdriver. Magnification is approx 2X and you don't pronounce the S in Fresnel but you do capitalize the F, just FYI.
