One Nikon Angled Eyecup - These are great for when you're not wearing sunglasses or eyeglasses; you'll feel as if you are locked in to the view, like watching a movie in a completely darkened room.
Like the description implies, this is one eyecup. You will need two of them to replace a pair of eyecups for a binocular, of course.
Compatible with the Nikon 7x50 ProStar II and 10x70 & 18x70 Astroluxe II & Astroluxe XL Series Binoculars.
