January 21, 2016
This Gel Pen refill DOES fit the excellent Pilot Birdy pen. It writes smoothly
and beautifully, and when used in such a small pen (which is super-convenient in
your shirt pocket) the tiny fine point allows one to write neater than say a
0.7mm regular ball point pen. Also, it is available in blue.
