4.5 inch (11.6cm) Replaceable Ballpoint Pen Refills Specially for ChaoQ Slim Series Stylus Pens (Pack of 10, Blue)

Refills work well and fit nicely in our home made pens. Good product.

These are super compatible for a pen I really wanted to keep. Ink color is great and dries smooth. I only used one refill so far, but I am confident these will last me a while!

The product came as promised in a day and worked perfectly.

I have a Colibri that used to be my dad’s. Trying to find a refill for it is impossible. This works well enough but you have to seat it as much as possible so the tip slightly comes out the bottom. The original fill is labeled Colibri A6, and this is the closest I’ve come to it.

The best I can say is that they do write. The ink on the pen tip seems to be clotting which can be a bit messy.
