The COCOIRO Letter Pen is built not just to write, but to express—capturing the “color of your heart” in every line. This newly redesigned Cocoiro comes in a new mature colorway, and includes a black ink refill (the former version came empty).
Key Features
Responsive brush-tip nib — Designed to handle the Japanese kanji strokes, the flexible tip dynamically reflects your writing pressure and speed, bringing out the unique character of each user’s style.
Smooth, comfortable body — With a flowing, rounded silhouette and soft-touch finish, the pen fits naturally in your hand, allowing for extended use without fatigue.
Refillable ink in five colors — Choose from five vibrant, water-based dye refills to match your mood or project. When the ink runs low, simply replace the refill: cap off the old one, screw in a new one, pop the cap to the back, and you’re back in motion.
Eight body-color options — Tailor the look of your pen to your personal aesthetic with eight stylish barrel finishes.
