Twsbi Diamond Mini Fountain Pen

The Twsbi Diamond Mini is a mid-range fountain pen that is basically a smaller version of the company’s Diamond 580.

The Diamond Mini is sold in a few different varieties including: the Classic, AL, and Clear. There differences between them are quite minor:

  • Diamond Mini Clear: Clear plastic cap and section
  • Diamond Mini Classic: Opaque black cap and section
  • Diamond Mini AL: Clear cap with aluminum section. Sells for about $10 more than others

Twsbi says that this small piston filler is about the size of an iPhone 5 when capped. That might have been a useful reference point in 2015 but it isn’t much help now! Then is about 4.5 inches long capped, or about an inch shorter than the standard Diamond 580. The Diamond Mini is in keeping with the popular Twsbi Vac Mini and Vac700R‘s relationship to one another.
