## Description

Fisher Space Pen Refill Black Medium SPR6. Blister Carded Space Pen Pressurized Printed Refill Black Med. Pack of 3.

Review: Excellent Everyday Dependability and an Embarrassing Admission - I keep a small Fisher space pen in my wallet. It's an excellent pen for everyday use. I keep it in my wallet in case I need to jot a quick note, address a letter, or the waiter forgets to bring a pen with the credit card receipt. It just works and most of the time I forget it's there. I realized in 2021 the same pen has been in my wallet since 2005. The embarrassing admission: When I realized I never refilled my pen ink after 16 years I ordered these refills. When they arrived I looked at the package, saw they were too long for the pen and cursed my not noticing when I ordered them. I kept them because they were just too small an item to bother returning. I figured maybe someday I'd get a full size Fisher pen. This month I found them in a junk drawer and realized the plastic bit that made the refill "too long" wasn't attached. It's needed for the full size pen, not the small one I ordered it for. By the way, the pen I ordered the refill for STILL hasn't run out towards the end of 2024.
Review: Good refills - This refill works great. My husband uses it in his uzi pen and loves it. It writes on just about anything and from any angle. It flows with ease and there is no leakage. He was tired of his pen needing to be scribbled with before writing to get it started and sometimes skipping. But this refill works every time.
