Product isn't the size described the 14mil sparkplug I was attempting repair slips completely into these coils without touching the walls I'd say they are at least 15 or 16mil. Completely unusable for the size they are described

Who knew you could use a chunk of spring for a helicoil insert. I was under the impression these were 1.25 inch, and they are nowhere near this. And a loose 14 mm at that. Not worth my time to send back so I'll figure out another use for them. Example, trash can.

These are what they say, kind of...While I assumed for the price that these were coming from China I still expected the order. I believe they must still be using child labor to package these because one package had 9 and one had 19. One child must be further along in their counting skills. Also these were all of the same depth, there was no assortment. I figure the kids must have not been paying attention to their directions, but what kid does?
