Thank you for viewing. ・【Antique】VISION 10x20 Binoculars Silver (with case) - Magnification: 10x - Objective lens diameter: 20mm - Field of View: 6° wide field of view - Model number: No.19719 ※ Other detailed operational checks have not been performed. ※ I have considerable nearsightedness (presbyopia), so I'm not sure if the focus is correct. Adjustment is possible. ※ There is mold and dust inside the lens and viewfinder. (It is not noticeable when observing) ~Product Condition~ I also enjoy antique items like cameras, and I received a part of an old collection from my uncle. Since these are not items I can handle, I will sell them to someone who can repair and maintain them. This is a retro and well-designed antique opera glass. How about using it not only for observation but also as a small item (vintage goods)? If you have any questions, please feel free to comment before purchasing. For those who understand old items, I will strive for a pleasant transaction and sincere service, so please refrain from purchasing if you are looking for a perfect item. ※ The contents are as shown in the photos. ※ Please negotiate for a price reduction if you are purchasing other listed items at the same time. ※ If you have any questions, please feel free to comment. (I will answer thoroughly within the scope of what I can answer) For those who can understand and agree to the above points, Please consider purchasing. Thank you. (I am also listing items that were stored at my parents' house) #Binoculars #OperaGlasses #VISION #ShowaRetro
