Zebra 4C Pen Refill
Stashable micro-pen
I don’t own the pen where this product is used as a refill, but I do use this in situations as an emergency back-up micro-pen.
I keep one in my wallet for the times when I don’t have a regular pen, and they’re the right size for a pocket-sized or mint-tin survival kit.
It has a good flow for a pen without a body. Not good for long-form writing, but it’ll more than do for a quick signature or short note.
