For superior optics, and a long useful life, you cannot beat optical glass magnifiers. The 3x Magnifying Glass – 3 Inch Diameter resists scratching and will provide superior optics for a long time. The glass lens is securely welded into the frame so these magnifiers are perfect for classroom use. The ergonomic handle allows for a secure grip and the 3inch diameter lens provides a large viewing area. Please note: Recently the manufacturer has relabeled most of their magnifiers. The 3x were previously labeled 5x magnification.
