See photos. The glass is clean except for dust which is ubiquitous. 77mm threads, and comes with the metal filter caps as shown.
There are two diopters with 0.33 and 1.3 strengths. They are somewhat heavy, made of metal, have no exterior damage and screw on/off cleanly. I used them for long focal lengths until I changed to extension tubes. Because of their weight, I wouldn't recommend their use on long focal length plasticky lenses.
Asking $150 (Paypal) for the pair, shipped in CUSA and will ship anywhere if you'll cover the difference. I can't seem to find these for sale new anymore, and I find only one set on eBay at this time.
