This is perfect and allows me to use my favorite Fisher pen.

Genuine Fisher refill

After reading some reviews online, I decided to try the fine point refill for my favorite fisher bullet pen.

Also, this, my first Fisher fine cartridge, is smoother to write with as compared to the Fisher medium cartridge.

This product goes part and parcel with my excellent collection of this remarkable Fisher Space Pen Series collection.

This refill also fights in the Fisher Space Pena and most other Fisher pens like the AG7.It's pressurized, so you can write upside-down or at angles

An authentic Fisher refill

oh it's just so great and lovely i just loooove this product
