Mighty Bright Loupe
BRIGHT LED LOUPE, 10x w/ DUAL LED, 25MM FOLD-UP
This 10X folding loupe in black plastic and aluminum has a pair of very bright white LEDs next to the 25mm lens. Runs on (3) button-cell batteries, included, and has a tiny wrench to help you replace them. Loupe and wrench stow snuggly in a foam lined plastic case. When folded, it looks like a standard coach's whistle, or a really big apostrophe.
