Why so many Lamy pens? Well I’ve got fine, extra fine and bold nibbed pens filled with sepia brown De Atramentis ink for natural history and another set filled with black for general sketching and for comics. Plus two for lettering and one with a non-waterproof black cartridge.
The Lamy ink in the cartridge just a bit more freely than the De Atramentis, so I use that for quick sketches when I’m not going to go add a watercolour wash, such as yesterday evening at the Wakefield Naturalists’ Society.
