Mighty Bright Loupe This 8X folding loupe in white plastic and aluminum has a pair of very bright white LEDs next to the lens. Runs on (3) button-cell batteries, included, and has a tiny wrench to help you replace them. When folded, it looks like a standard coach"s whistle, or a really big apostrophe. Forgive the package for saying 30X - if it didn"t say it, we wouldn"t have it!
