Optivisor Replacement Lens 3.5x 4” #10

I love it. As described, and received quickly.

I have a 5x which does the job in most cases, but this 10x is a must have for those teeny tiny crafts, hobbies, even for perfect manicures!

met my expectations and is easy to switch to lower power when this level isn't needed. Step up to this quality well worth it.
