Pilot Petit Pen Refill Cartridge (Blue Black Ink) × 3 Pack/total 9 pcs (Japan Import) [Komainu-Dou Original Package]

These cartridges are for the Pilot Petit pen, a marvelous tiny pen for carrying in handbag to be available for coffee-shop musings. These cartridges are custom to this particular little pen so they're a must. Nice to have along in case musings extend beyond current ink supply.

Finally get to use the foreign pens I bought while living overseas. Great value for not being a domestic item offered anywhere here in the states

Nice little refill for my pen!

Excellent ink. Very deep black. I use it with a Rapidograph pen to create sigils. Great pair.

I'm new to fountain pens so I am describing my experience with this product. This refill is great. Had no problems putting it in the pen. It started writing after waiting a bit with the pen upside down. The ink writes exactly the same as the original cartridge that came with the pen. The ink is smooth and dries fast.

I was ready to throw my pens away. I did not realize they were refillable. So glad i researched it. I love these pens and the ink flows so smoothly. Great for any paper

Great price. I hope to refill with a eyedropper.

I liked the size simple and easy to use
