Rite in the Rain Pen Refill - Black 37R

Very good refill, lasts a long time, writes even upside down, and fits perfectly with my pen. I recommend it, although the price could be lower.

I finally found a refill for my tactical pen that I bought a long time ago at Militaria. The refill works well despite long use, but nothing is indestructible. You can try a replacement refill, but it's just not the same.

Universal Fisher refills fit all Rite In The Rain pens and a number of other models that use Fisher refills. I tested them in rain, frost, and upside down – they are reliable and quite efficient, especially on special Rite In The Rain paper. I recommend them!

It fits every Rite in the Rain pen. I definitely recommend it.

It writes both upside down and in the rain.

Very good refill, lasts a long time, and allows you to write even upside down. I recommend it!

I haven't tested it in the extreme conditions suggested by the manufacturer, but it works perfectly in typical situations.
