MCM-2  All Metal ...2" inch glass lens with all metal construction and storage case.  Magnifying Glass with 5x magnification and protective storage case. This classic style magnifying glass has all metal construction scratch resistant glass lens that is easy to clean and sanitize, glass lenses may not be as optically clear as a optical grade acrylic lens but they are highly scratch resistant, and resistant acids and other corrosives, however they are more prone to damage if dropped. This model comes with a storage case. Is ideal for reading very small text, numbers or for inspection such as coin for stamp or silver marks, the 2" diameter makes it more ideal for inspection then for general reading because of the smaller field of view, unless you require 5x magnification due to low vision.
