If you have long-haired pets, like us, then you often wants to know exactly what you so everything has combed from the fur of his dog or his cat; or for the next visit to the vet, it's also important that you know nearer know if the animal so often scratching etc.
We have had a pocket magnifying glass, which worked quite well also, "has given up the ghost" but now and have to replace the "30x 60x professional LED clock jeweler loupe magnifier pocket magnifier Magnifier ..." ordered, with which we are very satisfied. (The delivery took place within a few days by the way).
For the relatively low price you get a magnifying glass, you open (and thus protect) can, and a (plastic) container, which ensures additional protection. Also included with a button cell battery and a key, which can easily open the battery compartment (if necessary).
A good resource for viewing small objects. From my side definitely a buy recommendation!
