My eyepiece case disappeared from my car a couple of years ago and I bought these to get me thru the hard times... decent Plossls with excellent fit and finish. Internally blackend with rubber grip (32mm and 20mm). 32mm has good nice eye relief for a longer ep, without much "blackout".
12.5mm - Available
20mm - Available
32mm - Offer Pending (Ron)
$25 each for the 12.5 and 20mm. $35 for the 33mm. $75 for all 3, shipping included (USPS) in US.
