50-pack refill kit for click pens

This 50-pack of Sherr XUL-Sherr-3443 ballpoint refills supplies black ink for retractable click pens. Each refill measures 3.9 inches long with a 1.0 mm medium point. The bulk quantity suits offices, schools, or home workstations that go through pens quickly.

Metal shell and fast-drying ink

A metal outer shell gives each refill a steady feel and protects the ink reservoir. The ink formula dries quickly to prevent smudges, keeping hands and pages clean during rapid note-taking. A protective cap on the tip stops leaks when refills are carried in pockets or bags.

Universal fit for spring-click barrels

These refills are shaped for standard spring-click and twist-action metal barrels, including glitter and rhinestone styles. The 3.9-inch length matches common pen bodies, so replacement takes seconds without tools. Buyers needing refills for rollerball, fountain, or proprietary cartridge systems will not be able to use these.
