OHTO Ceramic 0.5mm Ballpoint Pen Refil, Black (C305-Black)

Great refil Works as expected Fits perfectly

Very smooth and is an excellent alternative to the Mont Blanc meisterstuck rollerball refill if you use a M5 right handed 0.75 thread due to cut a thread into it. Trust me it'll fit perfectly.

Why I bought this product I ordered this as a refill for my ohto pen. It is the most reasonably price replacement ink on amazon and also it is part of Prime. I don’t want to order multiple packs so this is perfect for me. How is the product perform? The refill is as smooth as the original cartridge that came with the pen. So I’m happy with the product. Do you recommend the product? 100%. This refill will definitely fit and write like the original. It is great to write with and that’s why I seeking for a refill instead of throwing the pen away. I would buy the refill again once my pen run out of ink again.

Love this but the refill felt like I ran out fast.

This is a reliable refill ink for my AG Spalding Bros pen that I always have on me. I love the writing barrel of this pen - very smooth and sleek and a bit smaller than a typical pen. The tip of this refill is a great fineness - not too thin and not too thick and the refill typically lasts me a few months (I use the pen a lot). The black ink doesn't fade and only smudges on non-porous paper. I have a subscription now to this ink and am very pleased with it!

On my second order. Fits my vintage MICRO Ceramic Pen! Writes great . I had spent a long time trying to find refills locally for my favorite pen before discovering this Japanese brand on Amazon.

just works great

One of the smoothest writing experiences I've had. I've tried a lot of pens and inks and this has got to be in my top 3. It's very smooth and dark and dries fairly quickly. Used in my OHTO CR02
