The OHTO C-305P ink refill set offers a refined writing experience, featuring a 5-pack of ceramic roller refills with high-quality metal casings for dependable, long-term use. Each refill is individually stored in a hard plastic protective pipe (tube), making them safe to carry, easy to store, and convenient to keep on hand. Designed specifically for compatibility with OHTO CR01 and CR02 models, these refills provide a seamless match in both appearance and performance.
Each refill contains water-based blue-black (dark blue) ink and a ceramic rollerball tip, supported by Non-Dry technology that helps prevent the tip from drying out—even if the cap is accidentally left off. The internal structure is designed to limit air exposure to the core and ink reservoir, helping maintain fresh, reliable ink flow.
At the tip, the high-durability ceramic ball is corrosion-resistant and features a micro-textured surface that promotes strong ink adhesion, producing bold, smooth lines. This design helps reduce smudging and smearing while supporting clean, continuous writing. The ceramic ball's exceptional hardness resists deformation over time, allowing for smooth, consistent rotation and long-lasting performance.
Combining durability, reliable performance, and convenient individual protective storage, the OHTO C-305P ink refill is a practical and high-quality choice for your OHTO CR01 and CR02 writing instruments.
