Pilot Birdy Stainless Steel Body Mini Ballpoint Pen, 0.7 mm, Black Ink (BS-40S-S)

My favourite pens. Very small, so probably only useful for someone with small hands. They're a very useful size to chuck in a pocket or attach to a notebook.

A well made pen shipped from Japan for under a fiver! You can't complain at that. Fits nicely into the pen holder on my man bag.

Brilliant pen, value for money

Nice pen - a bit more solid than the similarly sized Zebra pen. Diameter is about 5.7 mm. Only downside is that it doesn't take standard D1 refills.

No problems

Writes fine. Smaller than I expected. No longer than an iPhone.
