Pilot Birdie Mini Ballpoint Pen
The Birdie ballpoint pen is a very slim and compact pen that asks to be carried around in your bag or purse.
Pen refills with a pen unit sold separately.
Measures about 11 cm in length. Diameter of the barrel measures about 0.5 mm.
This might be a really niche use case but I have a passport sized Traveler’s Notebook with the clip on pen loop attachment. The pen loop for this notebook is designed to accommodate a normal pen’s pocket clip but the Birdie is so slim that I can actually slip the body of the pen in this loop. On top of that, the pen itself is a little shorter than the passport sized notebook making it the perfect companion pen for quick notes on the go.
