Here's the lock that I have..

With a tension wrench

Comparing the size of my pick with the keyhole, way too big..

Here's the set that I've bought recently.

And the picture of the set shown by seller

Totally different from the one that I have, but it's only $12.65 for the whole set, I really have nothing to complain about it.
But the problem is it wouldn't fit to the lock I have at home. That's just the door lock of my home, still didn't have time to buy a training lock yet.
