This is the perfect magnifier for the collector on the go. The magnifying glass has an integrated lens cover that acts as a handle, so you can carry it in your pocket and slide it out when needed. The 5x magnification with wide viewing lens is adequate for most coin, watch, and stamp applications, and it is much easier to carry than a jeweler's loupe. Manufactured by Bausch & Lomb, the lens provides a clear and sharp image.
