Quick guide to choosing the right nib size:
If you write with very small handwriting, EF (Extra Fine) is recommended.
For everyday writing, F (Fine) is the most popular choice.
If you prefer slightly larger writing, M (Medium) is ideal.
B (Broad) makes a statement – perfect for signatures, headers, or shading.
