Here is a small set of binoculars with a few issues. Unless you enjoy being cross eyed, they need to be collimated. I've peeled back a bit of the rubber cover to have a go myself, but it's still a little bit off.
8 x 32
Field 7.5 degrees
131m at 1000m
Comes with a carry case. The eyepieces have nice little screw out eye cups.
Good question - I don't know.
They are covered in a kind of plastic/rubber stuff. You can sort of see in the first pic, I have peeled it back a bit to get to the collimation screws. It will need to be glued back down when the collimation is fixed.
