Cross Rollerball Refill. 2 Pack.

For writers who demand reliability, these genuine Cross 0.7mm medium-point refills restore the signature smooth performance of your Cross rollerball pen. Each package contains two archival-quality cartridges available in either classic black (#8521) or professional blue (#8523), delivering crisp, consistent lines that resist fading even after years in storage. The water-based gel ink flows evenly without skipping or pooling, allowing for precise signatures and fluid note-taking. Swapping refills takes seconds—simply unscrew the barrel, remove the depleted cartridge, and insert the fresh refill until it clicks securely into place. The 0.7mm medium point strikes the perfect balance between fine detail and comfortable writing pressure, reducing hand fatigue during extended writing sessions. These refills fit all Cross rollerball models including the Classic Century, ATX, Townsend, and Apogee series, ensuring compatibility with your existing pen collection. Don't compromise your writing experience when your original cartridge runs dry. These official Cross refills maintain the weighted balance and smooth glide that distinguishes your personalized rollerball pens from ordinary writing instruments. Each refill provides approximately 4,000 feet of writing—enough for months of daily use—making them an essential accessory for professionals who rely on their pens for important documents, personal correspondence, and everything in between.
