I have two sets, system 4 and system 6, in these rollup bags, the system 6 have the silver finish the whole way.
The system 4 are black on the end, just like that one, except all are like that (maybe two have silver, but can't see due to the paint on system 4)
So I guess it's intentional, and just a change in production.
Now I wonder if TopLoser also picks up tool-sets and resells..
