What comes in the box with the Rhomb Flame fountain pen?
The pen ships in a case for three writing instruments, together with a converter, two standard international ink cartridges, and a warranty card. The converter lets you draw from bottled ink straight away; the two standard international ink cartridges give you an alternative if you prefer cartridges. Everything you need to start writing is included.
Is the Rhomb Flame finish the same on every pen, or does it vary?
It varies. The Rhomb Flame pen has a stainless steel body that is individually flame-finished, so no two pens carry an identical surface. Diplomat states the effect is forged by real fire. The result is that the pen you receive will be distinct from any other Rhomb Flame pen, and from any photograph of one.
Which nib widths are available for this fountain pen?
The stainless steel nib is available in extra fine, fine, medium, and broad. All four widths are on the same pen in the same Rhomb Flame finish, so you choose the width that suits your handwriting when you order rather than having to source a separate pen for a different line weight.
Can I use bottled ink, and what do I need?
The pen takes bottled ink via the Diplomat plunger converter that is supplied in the box. When you need to refill, draw from any bottle and continue writing. Yafa also stocks Diplomat bottled ink in 30 ml bottles if you need a compatible ink to use with the pen.
Where is this pen made, and what warranty covers it?
Diplomat has produced writing instruments in Germany since 1922, and the Rhomb Flame fountain pen is made at Diplomat's production site in Cunewalde, Saxony. It carries a five-year manufacturer warranty, which begins from the date of purchase.
