Kaweco Fountain Pen Ink Cartridges - Midnight Blue (6-Pack)

Standard international ink cartridges for fountain pens. Midnight Blue ink, pack of 6.

Why This Exists

Kaweco Fountain Pen Ink Cartridges exist because running out of ink mid-sentence is annoying. These are standard international cartridges — unscrew the grip, pull out the empty cartridge, push in a new one, keep writing. Simple as that.

Made in Germany with Kaweco's reliable ink formula, these cartridges fit Kaweco fountain pens and most other pens that accept universal/international cartridges. Each cartridge holds 1ml of ink, giving you a predictable writing life before needing a swap. Six cartridges in a pack means you're sorted for a while. Midnight Blue ink — darker and more sophisticated than standard blue.

What Makes It Good

• Standard international fit — works with Kaweco and most universal cartridge pens
• Midnight Blue ink — deep blue for professional writing
• Quick dry time — minimal smudging
• Controlled flow — reliable performance, not too wet or dry
• 1ml per cartridge — predictable ink capacity
• Pack of 6 — good supply for regular use
• Easy to swap — no mess, no ink on fingers
• Made in Germany — Kaweco quality standards

Who This Is For

Perfect for Kaweco fountain pen owners or anyone with a pen that accepts standard international cartridges. Ideal for everyday writing, office use, or travel.

Specifications

Note: These are short standard international cartridges. Check your pen's compatibility before ordering — proprietary cartridge pens (Lamy, Parker, etc.) won't accept these. Works in Kaweco rollerball pens as well as fountain pens.
