Opticlens Brand handy 5 x 7 inch page magnifier. Excellent for reading the fine print in books, magazines, maps, telephone directories, and recipes. They also work great for use in light-duty solar projects such as starting campfires, DIY solar cooking, and solar heaters. They are made from flexible high-quality, optical-grade PVC. This allows them to be thinner with less distortion as well as being lightweight and easy to hold while using. Optical PVC is virtually shatterproof for safety and peace of mind. Lens Specifications: Approximately 5″ x 7.00″ (Inches). Thickness: 0.4mm. Material: optical PVC. Groove pitch: 0.3mm. Focal length: 300mm. Magnification: 3X or a 300% increase.
