Magnifying Glasses. Features: Have two independent lenses with 20x magnification power each. The distance between the lenses can be easily adjusted. If necessary, one or both of the lenses can be moved aside so you can take a look at your work without magnification. The lenses are made of quality optical plastic, a material that is in no way inferior to glass in terms of purity and transparency. At the same time, in terms of durability and endurance optical plastic is superior to glass. Each of the two lenses has individual LED illumination sources. Illumination is bright enough to allow for working in a poorly lit environment. The kit includes: Magnifying Glasses, CR1620 batteries - 4 pcs., User manual and Lifetime warranty.
