If you love smooth-writing rollerball pens, you’ll want to try these Schmidt 888 M refills.

They come in a 2-pack with red ink and a medium 0.7mm tip – perfect for signing documents, grading papers, or just adding a pop of color to your notes.\n\nSchmidt’s a German brand that’s been making refills for over 50 years, so they know their stuff.

The 888 M uses a ceramic rollerball and stainless steel tip for a really consistent, glide-on-the-paper feel.

The ink is liquid-based, so it flows nicely without skipping.\n\nThese are “safety” refills, which means they’re designed not to dry out even if your pen doesn’t have a tight seal.

Great for pens that don’t have caps or if you tend to leave your pen uncapped now and then.\n\nEach refill is about 4.35 inches long and fits pens that take standard Schmidt-style refills.

They’re made in Germany and come in a blister pack for protection.

If you’re picky about how your pen writes and want a refill that’s reliable, vibrant, and smooth, these are a great upgrade from generic ballpoint refills.
