These nuts were packed really well. In individual bubble wrap. However, due to the high salt levels in the Midwest, the black finish only lasted a few months before turning into a "patina" and sticking everything to the stilettos. Recommended for those who do not live in a salty climate. Antiseize works wonders. They are no longer sticky but are still the color of rust. Another problem I encountered is that the corners are slightly rounded. Not the perfect 19mm/3/4in, not rounded to the point where it can't be used, but yes the corners are a little crumpled.
