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

I liked the size simple and easy to use

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.

Very good product! Excellent ink cartridges that last a while and work well with my pens.

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.

Bought the fountain pen for my daughter. She's loves it and uses a lot of these cartridges. High quality, very nice colors. Will buy again.

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
