Check the listing for details. 30X Illuminated Pocket Microscope Magnifying Magnifier with Focus Wheel works!. Condition: Used. Listed at 25.00 USD. It had batteries in it that had started to leak. I installed new batteries for testing and the tool does work. I will not be shipping with batteries in it. I used the tool to get a closeup of a fabric patch I had. I was able to capture photos through the lens. Pretty cool. The tool was initially distributed to Bridgestone dealers so we could examine the "micro cell technology" in the tread of the Blizzak tires.
