Overkill but Contained What I Needed
I was surprised it came from China and opening the package was difficult due to the amount of cellophane tape used to seal it, but other than that it allowed me to repair my old watches economically.  Spring bars in excess of 21 mm are hard to find.  I now have enough spring bars to last a lifetime but I'll never waste time and gasoline driving around town again looking for someone that has what I need or will repair my watch at a reasonable cost.
