My favourite black pens ever! These pens are amazing – they are definitely permanent and waterproof, which means you can paint over them with a watercolour (or inktense or brusho etc) wash and the lines will not bleed. They come in different sized nibs so you can choose between thick or thin lines.
Other brands have stopped working quite quickly for me as the point went, but these go on for ever (assuming you draw like I do – no responsibility taken if you don’t!).
Lovely to handle for drawing, sketching and writing.
This is a pack of 5, with nibs 0.1mm, 0.2mm, 0.3mm, 0.5mm and 0.8mm
