## Questions & Answers

**Q: I just bought your TWSBI 700 Medium tip pen, and I'm interested in a bolder tip for calligraphy... How bold is this tip compared to the Medium?**
A: I don't think you would want to use the broad nib for calligraphy.  You want a pen with a stub or italic nib and I would recommend at least 1.9mm.  TWSBI has a 1.1mm stub, which is ok for calligraphy.  I would consider Pilot Parallel or Kaweco's calligraphy set, as you can try several nib sizes without breaking the bank, or a Speedball dip pen with a variety of nibs which can be bought cheaply.
