Faber-Castell Standard Ink Cartridges for Fountain Pens, Erasable, Premium Quality, Easy to Refill, Smudge Free, Ideal for Personal & Office Use, Royal Blue, 6 Cartridges Per Pack - Blister of 3

Specifications: short international cartridges compatible with pens that use standard international short cartridges; erasable royal-blue ink for easy edits; clean, consistent ink flow; three boxes per blister pack, with six cartridges per box (total of 18 cartridges). Made in Germany for everyday school writing and office use.

Erasable ink is formulated to be erasable with a suitable ink eraser. Erasing performance depends on paper quality and the eraser used. For best results, use a compatible eraser and light erasing strokes; some papers and erasers may show residual marks, especially on glossy or coated surfaces.

These are standard international short cartridges, so they fit most fountain pens that use international short cartridges. If your pen uses long international cartridges or a proprietary converter, these may not fit without modification. They’re ideal for school pens and everyday writing devices that take standard short international cartridges.

Remove the pen’s cap and existing cartridge or empty converter. Shake the cartridge gently, then insert the narrow tapered end into the pen’s feed and press or twist until ink flows into the nib/feed. If your pen requires a converter, you’ll need to use one in place of the cartridge. After insertion, allow a moment for ink to begin flowing before writing.

Store unopened cartridges in a cool, dry place away from direct sunlight and heat. Keep them in their original packaging to protect against moisture. Once opened, use them in a reasonable timeframe and keep the pen capped to prevent ink from drying at the nib.

Yes. The ink is non-toxic and produced in Germany for general consumer use. As with any ink, avoid ingestion and keep out of reach of small children. Teachers and students can use them for regular writing and editing tasks.

Ideal for drafting, drafting corrections, classroom activities, and editing written work. The royal-blue color stands out for edits or annotations, and the erasable feature helps students make and remove changes without wasting pages.

The ink is designed to dry quickly and reduce smearing, but smudge resistance can vary with paper type and writing pressure. On standard copy paper, you should experience minimal smudging after drying, though very glossy or highly absorbent papers may behave differently.

Yes. The pack comprises three boxes of six cartridges each (18 cartridges total), which generally reduces the cost per cartridge and is convenient for term-long use in schools and offices. Bulk packaging also minimizes refill interruptions during busy periods.

Both are Faber-Castell standard international short cartridges designed for ease of use in school and office settings. The primary difference is ink color and intended use: the Royal Blue erasable variant is ideal for edits and notes, while the Black variant provides a classic, non-erasable appearance suitable for standard writing.

If you prefer non-erasable royal blue ink, this alternative offers the same color with a non-erasable formulation. It may be chosen for documents where permanence is desired or where an erasing option is not needed.
