I collected a few Mont Blanc pens, but many didn’t feel very substantial and accidently dropping one usually caused damage.
Then I discovered Retro 51 pens. They are extremely well built and many have interesting themes. Retro 51 does several for the Smithsonian. For instance there is a Vega after the red Vega plane Amelia Earhart flew over the Atlantic that is at the Smithsonian.
I guess it became a hobby/obsession. I have about 50. They ranged in price for me from $35 to $55.
They do special editions that are numbered and they only produce a couple hundred to maybe 2,000 depending on the expected popularity. They often sell out in an hour. I just bought the red dragon, which they only made 300, and I know I got one of the last ones.
