Extra Fine (EF)
Writers who value a delicately fine line will appreciate our Extra Fine (EF) and Fine (F) nibs. Both have a rounded tip, making them easy to write with in almost any hand position.
Fine (F)
With its rounded tip our Fine (F) nib creates delicate lines that are slightly wider than our Extra Fine (EF) option. Easy to write with, this nib suits all styles.
Medium (M)
Our Medium (M) nib has a rounded tip that creates uniform lines suited to all handwriting. You may also appreciate the smooth flow and variance of our Oblique Medium (OM) nib.
Broad (B)
Writers who prefer a thicker line will appreciate the strong Broad (B) nib. Alternatively, the particular cut of our Oblique Broad (OB) nib may offer a smoother finish.
Double Broad (BB)
Prefer a heavier handwriting style? The strong Double Broad (BB) is an excellent choice, while the particular cut of our Oblique Double Broad (OBB) may offer a smoother flow.
Oblique Medium (OM)
Perfectly suited to writers who like a medium width line, our Oblique Medium (OM) nib offers an incredibly smooth flow. For those who prefer less variance, try our rounded Medium (M) nib.
Oblique Broad (OB)
The angular tip of our Oblique Broad (OB) nib is ideal for those who value a strong line with pleasing variance, or writers inclined to slant left. For a more even finish, try the Broad (B) nib.
Oblique Double Broad (OBB)
Ideal for heavier writing styles, our angular Oblique Double Broad (OBB) nib offers a smooth flow and strong lines. For less variance, try our rounded Double Broad (BB) nib.
