FlexStroke Brush Calligraphy Pen

The FlexStroke Brush Calligraphy Pen redefines what a brush calligraphy pen can do. Engineered with a proprietary dual-fiber nib — a firm outer sheath surrounding a softer inner core — it delivers predictable, responsive flex that adapts to your pressure in real time. Whether you’re working slowly on ornamental lettering or quickly sketching out loose, gestural script, the FlexStroke responds accurately and instantly. The ink reservoir system is pressurized to maintain a consistent flow rate regardless of how you hold or angle the pen, eliminating the frustration of dry spots and blobs. The ergonomic triangular grip section in soft-touch rubber reduces hand fatigue and improves control during long sessions. Water-based, acid-free ink formula is safe for archival use on papers, cards, and art boards. Refillable via a convenient twist-off barrel — compatible with our own FlexStroke refill cartridges as well as standard Tombow-style refills. Works on smooth, semi-rough, and textured surfaces. Available in eight ink colors. Ideal for brush lettering, modern calligraphy, and illustrated journaling.
