Review on Titan TIT45252 Black Vacuum Cap Assortment - 80 Pieces for Effective Sealing by Chris Jenkins

They stink. So what. Also burned gear oil. ;) Yes, they smell bad. Yes, the smell is stronger and more pungent than you might expect. You probably think to yourself that this won't bother you. but maybe. If you or someone who works near you is very sensitive to odors, this product must be stored in sachets. In a typical auto shop environment, bad odor is not a big deal. This kit is still profitable and convenient.
