This model is Pelikan's signature striations with black cap and filler knob - the Black stripes are actually transparent, so when the pen is held upto light, you can see the level of remaining ink. Also, you can just about see the mechanism moving through the stripes when you turn the filler knob.
See above for the full product description.
The 1.1mm italic nib offered here has been ground by Niche Pens from a broad M400 nib. It has been made by us into a 1.1mm italic nib for an additional cost of £35.
