Rite in the Rain Ballpoint Refill

Rite in the Rain All-Weather Pen Refill - Black Ink - (No. 37R). Fits most Rite in the Rain All-Weather Pens with replaceable cartridges. Black Ink.

Rite in the Rain refill cartridges are made by Fisher Space Pen Co., and per Rite in the Rain feature a specially formulated ink tweaked from the standard Space Pen Refill to work optimally on Rite in the Rain all-weather paper. Personally, I enjoy the Rite-in-the-Rain ink as I find it less viscous.

Pens feature the same adapter as Fisher refills, to allow you to use them in many other pens that are compatible with Parker-style refills.

Made in USA.
