They're pretty nice, shiny, fit snugly onto the peg, but there's this annoying burr on the side of them, pretty sharp too, I cut it off with a flush cutter and finished it with a little file. For this price I'd expect them to be 100% perfect, €7,90 for two tiny pieces of black plastic and they can't even bother to cut the burrs off. And the packaging they came in was pretty wasteful, the bag was gigantic compared to the knobs, it could've been 5 times smaller and there'd still be plenty of room left.
