Finally, a magnifying glass and, moreover, with lighting! Bin 70 years and need a long time reading glasses. And sometimes a magnification for fine print on various Pflegeproduckten or descriptions. This magnifying glass with light is so handy and shirt pocket formally, so I recommend it to anyone as an aid in similar use like me! The insertion of the mini battery no problem if you have a mini screwdriver Kreutz; something should be present in the household.
