Great pen for refill

These are not rollerball pens. They are felt tip pens. With felt tip pens, when you write slow the ink would get thicker on paper. When you write fast, it would be streaky.

Got these to replace the ink cartridges of several of my gel pens. All of the refills were fresh and not dried out. They worked well and the smoothness of the ink was similar to the original refill.

Works well

Tengo una pluma de recuerdo, es a apreciada por mi, no había encontrado repuesto que le sirvieran, ahora puedo usar mi pluma y con el color de la tinta que me gusta.

Fits and works great for my pens.

in measuring my old one these were correct to size to fit the pen I was needing it to fit.

Great item, works well

Funzionano perfettamente

Estou usando sem nenhum problema.

Great inks, write exveptionally well, fit my pen (custom built one for me) and surprisingly I enjoy using these inks. I have no faults in them, i do suggest and hope you enjoy them as much as i do, keep in mind the fitting of them pre purchase.

Die Tintenroller-Minen sind von toller Qualität und schreiben sehr flüssig. Die Tinte trocknet schnell und verläuft nicht, ideal für präzises Schreiben. Wirklich ein super Produkt, das ich gerne wieder bestelle.
