These compact, lightweight binoculars can be carried around like a mobile phone. They fold up for easy portability, making them suitable not only for concerts but also for sports観戦 and overseas travel. Adjusting the interpupillary distance, focus, and diopter is simple. I bought these new for a concert and used them only once. I'm selling them because I haven't had the opportunity to go to another concert since. - Brand: OLYMPUS - Model Name: Trip light 8x21 RC II - Magnification: 8x - Color: Champagne Gold - Accessories: Soft case, strap, eyepiece cap
