Some of the wrenches came with some chemical stains on them, not sure what it was, but nothing that I couldn't rub off. One had some black "goo" that I had to scrape off with a thumb nail; The carrying pouch has that awful "straight out of china" smell that takes awhile to go away and make your hands smell, do not like that. They appear to be decent quality wrenches, but obviously not "snap on" in feel. Used a few on a brake job and car repair and they worked without incident. Good price for a large number of wrenches.

I have not seen a spider or a bug of any kind since I sprayed this product both inside and outside of the house.
