Three Amigos? Well in the movie, the Three Amigos are the good guys. Today’s three pens belong to the Retro 51 Bandit series. A Bandit is not typically a good guy. Did Robin Hood pop into your head? But bandits can still be friends, so I say these three Bandits can be Three Amigos. Retro 51 started an impressive 27 years ago. Still we can not consider any of their pens vintage.
