This is Kenko's binoculars "10x25 DH SG". The magnification is 10x, and the objective lens diameter is 25mm. It's a compact, foldable, dual-axis roof prism binocular. Suitable for a wide range of uses, such as travel, concerts, and theater. The actual field of view is 5.6 degrees, and the brightness is 6.25. This is a consignment from my husband. He used it once to watch a bodybuilding competition. I think the condition is good, but please understand that this is a used item stored at home. - Brand: Kenko - Magnification: 10x - Objective lens diameter: 25mm - Accessories: Case - Model: 10x25DH-SG There are no instruction manuals or warranties.
