Mini in Smoke trim

• Vacuum filler type fountain pen.
  
• Comes in EF, F, M, B, stub1.1
  
• Roughly the same height as an iPhone 5 when capped.
  
• Slightly longer when cap is posted on the pen. 
  
• About 1 inch shorter than a Diamond 580 fountain pen.  

A quick no brainer guide in choosing nib sizes in an overly complicated fountain pen world:

If you write small, go with an EF
For the normal writer, F is the most popular
If you tend to lean on a bigger font, M will be perfect
B is for statements!! Sign a check in B, write a header in B, do some coloring/shading in B
Stub nibs are italic in writing style (have a special card or invitation to write?)
