NICE! Can't wait to see what you got.
Well the quality of pics can't compare to yours, but....
All the tools were sealed in original packaging, and well packed. The Koken ratchet has very very light resistance when ratcheting. A nice handle that is like a very very hard rubberized plastic. The sockets are very shallow, allowing access in tight spaces, and the universal is probably the best design I've ever seen.
Nepros vs KTC ratchets....
Finish- Nepros wins....the Koken falls in between KTC and Nepros in terms of appearance. More towards the Nepros end of things though.
Ratcheting action- Koken wins, very little resistance, both 36 tooth designs.
Koken non quick release (which I prefer).
Handle- Nepros wins, due to a slicker more durable design, but only by a hair. I like fat handle ratchets.
Durability- Tell you guys in a couple of years....
Overall- Koken, because I like non quick release ratchets, due to the fact they hold the socket with less play.
Koken spinning T-Handle- Simply awesome

best T-Handle ever....
Vessel Impactas- Haven't used them yet, but could bail you out in a tight spot that needs and impact driver. Quality, innovative design by a reputable screwdriver manufacture.
I picked these up on my way to work (600 miles from home), so it's gonna be later rather than sooner getting some side by side Nepros vs. Koken socket picks.
