The construction and materials are good, the magnification is probably closer to 10X and it doesn't look like or feel like a piece of junk.

The product consists of 2 identical units each in their own cardboard outer box and plastic keeper box. A transparent plastic lid hinged on a black plastic base with foam insert cutout to hold the loupe.

The loupe case is of metal construction with even and uniform chrome finish,  screw fastener to the hinge and clear even lens.  The text 30x-21mm is ink printed onto the loupe cover and can be rubbed off with a fingernail.  A ring screw fastens the lenses and spacer into the loupe frame.

In use the loupe is held very close to the eye and the subject about 1 inch from the lens.

The diameter is about the size of a quarter, fits easily into a pocket and would be handy to take about when looking at jewelry, stamps, coins, pellets, electronic components, insects or other small objects.
