Poor packaging !
ThIs screw set is food quality and seem to get a better grip in plastic parts than the stock screws that came with my rc car kit ! There is a few sizes I needed it didn't have but all in all is a good set. The package came in a padded plastic envelope and some of the screws had come out of the plastic case and were loose in envelope and all the screws in the case were mixed up had to go through them all and sort them out by size and counted them and some were missing if it wasn't for that I would have given it five stars !

Terrible. Rusty. Junk
Updating my original review. They looked good, for two days. Explain how a bolt that is supposed to be stainless rusts? Absolute trash.
