The Fountain Pentel features a unique double-sided 'delta'-shaped nib. This has a stronger support on one side than the other, meaning there is a subtle but noticeable difference in writing feel. Choose to write with one side and it feels more flexible, while the other side will give a firmer response.
Over time the nib will wear to the style of the writer, offering a unique writing experience.
Assorted set of 3 contains one each of blue-black, dark grey and sepia.
