These refills dropped right into my Kikkerland pen with zero fuss, and the black ink is perfectly consistent. I’ve been erasing and rewriting the same grocery list all week, and it still works flawlessly. Just glad I grabbed the 3-pack because I'm already reaching for a second one.

I've been using these refills for a couple of weeks now and the ink flows just as smoothly as the original cartridge that came with my pen. The erasing still works perfectly after rewriting over the same spot multiple times, which is exactly what I needed for my daily to-do lists.

The refills slide into the pen without any fiddling, and the ink flows evenly while still erasing cleanly. I’ve used them for weeks of daily notes and the black stays sharp, not faded. Got my money’s worth out of that three-pack for sure.
