WALTEX1-1/4 x 1-1/4 Square Shaped, 3X Lens, In A Sliding, Pocket Sized, "Pop-Up" Magnifier

For a long time, I could not find these, and I believe the new ones, as here, are exactly the same but marketed by a different company. This is light, very easy to hold, can manage when dropped, and seems not to get scratched on the lens surface. I have a couple of older ones that I use to study manuscript illumination and I recommend them as accurate magnifiers that don't fatigue the hands.
