I have a set of Fujinon Bat Winged Eyecups. I know that they fit both the 10x70 and the 16x70 Fujinons, as I have had both pairs in the past.
I am not sure if they would fit other Fujinons ie. 7x50's.
These are extremely well made, they screw into the eyepieces. They are also very, very hard to find. If you own a pair of Fujinon's, you should have these.
The price: $80.00 plus postage ( I paid more 4 years ago)
