### ⭐⭐⭐⭐⭐ Review
*by T***R on 19 November 2024*

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.
