RKS pens come in both Rollerball and Fountain options. All the rollerballs use German-made Schmidt 888 Safety Ceramic Rollerball Plastic Tube refills, which is called a “universal” pen size, available online. You may find various point sizes online as well.
My smaller pens take a #5 (Haiku, Limerick, Classic, Legend L-10 and Quatrain -not it’s larger counterpart) while the larger collections use the #6 size nib (Grand Quatrain, Epic, Ballad and Legend L-14, L-15 and L-16).
I have made a handwriting sample using all of our nib sizes (in a #6, but expect the same point size and line variance from a #5) for your consideration.
Extra Fine nib (EF): ideal for small handwriting, elegant.
Fine nib(F): a great choice for most handwriting.
Medium nib(M): our most popular nib, more noticeable than the above.
Broad nib(B): best for larger handwriting. Broad nibs make a statement.
For line variation, select a stub italic nib.
1.1mm stub nib
1.5mm stub nib *not available in 18k gold nibs
