This Pentax eyepiece has only been used once or twice and is in mint condition. It comes with original box, end caps, plastic case, paperwork, and all original packing materials, right down to the styrofoam peanuts. Even the new eyepiece smell is included!
My diagonal has a brass compression ring, so there are NO marks or scratches. This eyepiece is only about a month old, so it is still as good as new. I have a pair of these (too big for bino viewer) so I am selling one. $200 - Cashiers check, money order, or PayPal accepted. Personal checks will need a week or so to clear.
