Frequently asked questions
Will these fit my fountain pen?
These cartridges use a 3.4mm bore (international standard). They will fit most pens that accept "standard/international" cartridges. If your pen uses proprietary cartridges or a converter only, check the manufacturer's guidance.
How fast does the ink dry?
The quick-drying dye-based formula is optimized for minimal smudging. Dry time depends on paper type and stroke thickness; on standard notebook paper expect a few seconds for thin strokes and slightly longer for heavy ink flow.
