Up for your consideration is this FIS (Fiber Instrument Sales) 400x Handheld Microscope with 1.25mm and 2.5mm Adapters. As an estate sale find, it is in GREAT condition overall with normal signs of wear from general use. Comes with its original zip carrying case. Please be aware that there is an “X” marked on the end screw of the battery compartment and there’s a repaired tear on an interior, self-fastened pocket. Although I have not personally tested it, I have been assured by the previous owner that it works with no issues. I have also included the Production Specification sheet (which was downloaded and printed). Please examine ALL photos carefully for detail or any other flaws.
