Use this trio of large to small magnifying glasses for an array of hobbies and scientific pursuits! All are heavy, quality glass with wire frames. Diameters: Large, 4”; Medium, 3”; Small, 2 1/2”. The smallest magnifier has a single piece metal handle, while the medium and large magnifiers have lighter-weight plastic handles. All are in relatively good condition; however, the medium magnifier has sustained some visible scratches. The power is not marked; the only marking is on the large and small magnifiers, which read “JAPAN.”
