I have no idea where he got them, first off:
To me though, it looks nothing more than a military pistol cleaning kit (or 5.56 kit with most of it replaced for a pistol bore brush). The brush itself is most likely generic. Looks exactly like the issue 9mm. I doubt a USP 9mm or .45 kit would have any differences what so ever.
$20 seems a touch high but not out of reason to me. I got a 5.56 kit used for $15ish.
