For an example, the factory made 100 seasprays in last round, and during the QC, 10 of them already failed, then this round would be considered failure. But out of the rest of 90, there are some good ones some bad ones. It is impossible to fail 100%. Then some of them will be shipped out, sold in bulk, then examined by sellers to make sure "they look good" and dump the faulty ones.
As a result, they are *looking good* but out of the *failure round*

. QC is usually a sampling check procedure, so not all will be examined.
I don't buy loose figure at all, but if you look at RK's seaspray pic on their sale page carefully, you should already see some scratch on the head.
But different people have different standard on toy quality. So in some sellers perspective, they might think they are selling loose figure as doing a great favour for you by selling cheaper and earlier.
You can't compare the one in kmart and a loose figure, but if you compare 100 boxes from kmart and 100 loose figure, I am pretty sure the statistic difference will become clear.
