Ooly Color Write Colorful Fountain Pen Ink Refills, Set of 8, Multicolor Refills Compatible with Ooly Fountain Pens Only

I like everything about this ink. If you change the color in only one fountain pen be sure to rinse the old ink out of the pen head first or your color will start out muddy. (This box has a variety of colors.)I bought the set of pens so I can keep the same color ink in each pen. They are a good value and work very well.

I bought the OOLY coloured fountain pens for my daughter, a few Christmas's ago and she loves them. They are mostly used for art projects that she does on her own. I bought the pens because I knew OOLY made refills, so we wouldn't be contributing to the landfill by throwing away pen after pen. The cartridges are great, you just pop them in the pen and make sure you hear the 'pop' so you know the cartridge is connected properly. She loves the colours and the price is great. Highly recommend.

Very pleased with these ink cartridges! The violet is in the picture above. No issues with leakage or blotting. Very clean and dry as quickly! I would recommend this ink!

The colors are consistent until they are gone.

Good pen and refills are substantial -have enjoyed this writing utensil and glad the refills are available to continue writing quality.

Happy wife, happy life. She likes it, I love it.

I love writing with a different color every day in my journal.

Why, it's exactly what was needed for the Ooly pen. I'm going to write things with it, but not free reviews.
