Neck Magnifier. Great for all types of needlework. Large 4” lens magnifies 2½” times; plus a small close-up lens in the base for detail work. Adjustable nylon cord to hang magnifier around your neck. The acrylic lens is lightweight and comfortable to use. Because these are acrylic, some small scratches and flaws are not unusual. These do not detract from the quality of the magnification or view through the lens.
