It’s Rite-In-The-Rain
Rite-In-The-Rain is good stuff.A little expensive for everyday use in industry but I stick with it because I’m outside in all kinds of weather and it just works.The red is a nice, visible shade of red for when you want or need a red pen. It fits seamlessly in a Gerber Impromptu pen that has seen some hard use over the years. The point is fine for those of us who tend to write small sometimes, and it seems to be flowing just fine on day one.If you want a red, pressurized refill for any one any will take Rite-In-The-Rain this is a good choice.

Perfect Refill!
I got Rite In the Rain pen and some Fisher Space Pens. They are the same NSN number and they just work. Been using these for years and never let me down.

I won’t use any other brand on-duty
I’ve had my Gerber tactical pen for over 10 years and have only had to refill the cartridge a handful of times with Rite-in-Rain pen refills. The ink quality is outstanding, and the value for what you get is unbeatable. These refills have proven to be incredibly durable and reliable, even in tough conditions. I will continue buying this brand for the rest of my law enforcement career. Highly recommended for anyone needing dependable writing tools.

The gas charged cartridges live up to their promise.
Be sure to check color, I didn't. My fault.

Do you write in the rain?
Truth is I don't care. Some time ago I bought that fancy Gerber pen. The one with the glass breaker tip on it. It uses these inserts, so this was a replacement for the original and I have to say, it produces smooth consistent fine ink. It's a good pen. Regardless of what pen you're putting this into, assuming it's the correct size, it writes well and lasts quite a while. The writing in the rain claims haven't been tested but that's not why I bought it. Like I said, it's a good pen.
