The Cross pen refills in this six-pack contain archival-quality black ink that resists fading for decades. Each cartridge measures 38mm in length and fits all Cross fountain pens manufactured after 2010, including the Bailey, Calais, ATX, and Townsend models. The hermetically sealed design prevents ink from drying out even when stored for extended periods.

When inserted into your pen's grip section, these cartridges create a water-tight seal with an audible click, preventing leaks in your pocket or bag. The ink flows at a consistent rate across various paper weights (20-32 lb) without feathering or bleeding through, making these cartridges reliable for everything from signing legal documents to sketching in journals. A simple rinse of your fountain pen nib with cool water between cartridge changes prevents clogging and ensures smooth starts.

Each black ink cartridge provides approximately 4-5 pages of continuous writing or 2-3 weeks of regular use. The proprietary Cross ink formulation contains UV stabilizers that maintain color intensity when exposed to light, important for archival documents. These cartridges arrive in a compact storage case that protects unused refills from damage, keeping your personalized writing instrument performing at its best year after year.
