I have had my fill of Gem blue star blades. I have had 2 dispensers from 2016 unopened every blade in the dispensers was bad .Rough as cob not even able to get trough the first pass , and rusting very quick took one out and left it on the bathroom counter for 10 mins to get a Schick injector to finish the shave and it was already staining were the water droplets were. I don't know if they mixed up 2 facet blades with 3, and can they be bad after only 7 years ? I have 4 more unopened dispensers
