The seller of these clearly has no experience in engine building/rebuilding. A nick as small as .5mm on the skirt or in a ring land is the difference between usable and scrap.

The rods are likely usable; I always have them shotpeened and the bigends resized. But no way I'd trust alloy pistons rolling around in a box of steel conrods - no question which part is going to win that battle.
