Need a super hand every day lettering and lining pen? These technical drawing pens by Zebra are my new favourite! Choose from 0.5mm or 0.8mm nibs- with ink that's jet black and: - Archival Quality - Fade Proof - Waterproof - Acid Free The finer nib makes them a super useful size for lettering in your Bujo. This listing is for ONE PEN- but you'll probably want a couple after you've tried them out! ;) Choose from 0.5mm or 0.8mm at checkout.
