The nib is the part of the pen that touches the paper, and it has more effect on the writing experience than any other specification. BAOBO currently offers an F nib across the collection.
F stands for fine. It is a balanced everyday width: controlled enough for notes, correspondence and a personal journal, without the extreme precision of a needle-point nib. The exact line depends on the paper, the ink and the pressure you use, so no fixed millimetre width is promised.
If you already write with a broad or very fine nib and know that you prefer it, wait for the additional sizes rather than choosing a pen that does not suit you. Additional nib sizes are planned; they will appear on each product page only when they are available to order.
A fountain pen writes with very little pressure. Let the nib rest on the paper and guide it; pressing down can misalign the tines. Use a fountain-pen ink and flush the pen when changing ink or storing it.
