I only ever used the scope alignment bars (never the lapping tools/paste, etc). And I only used those bars once per set. In other words, it's functionally "new".
"Mr. Kokopelli" was an older gentleman when I spoke to him and his website is no longer working. I hope he is doing well. He made a fine product.
Note that these are 1" and 30MM sets (sorry, no 34mm) They are very heavy as you would expect for a huge steel bar and aluminum bar stock.
$150 per set shipped CoNUS; Both sets for $275
