Thank you for viewing. ・【Antique】SUNRISE 10x20 Binoculars, Silver. - Magnification: 10x - Objective Lens Diameter: 20mm - Real Field of View: 5° wide field of view - Model Number: J-B231 15800 - Made in Japan ※ Other detailed operational checks have not been performed. ※ I have significant 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's 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 items I can't handle myself, I'm selling 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 concerns, please feel free to comment before purchasing. For those who understand old items, I will strive for a smooth 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 price reductions 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) Please consider purchasing if you understand and agree to the above points. Thank you. (I am also listing items that were stored at my parents' house) #Binoculars #OperaGlasses #SUNRISE #ShowaRetro
