ZEBRA01022 1 mm Ballpoint Pen Ink Refill - Black (Pack of 2)

Can write on paper.

They work as intended, they're pretty good value, and they fit in my favourite pen.

Ideal for my Zebra retractable pens.

This product was excellent for writing with. Long lasting and value for money.

Not a lot you can say about a refill for a pen.Writes great and fits my Zebra F710. Metal bodied rather than the plastic bodied one that was in the pen originally, so you could regard that as an ungrade, I suppose.
