I bought 2 sets of these from the US for a pretty penny a few years back. These have never been mounted and have sat in the pack for best part of 10 years. If you really really look close there are some minor, and I mean minor imperfections, which you can just make out on the edge of the centre ring. They are not scratched on the outer facing at all.
Consist of 2x12mm rings each 8.8g and 1x 6mm which is 4.3g
In the 1" size these are now like the proverbial rocking horse shit.
£8.50 each posted 2nd class within UK or all for £23 posted
