Pack of 12 Gel Ink Refill for Retractable Pens, Medium Tip Point 0.7mm, Black Ink, Fits Retractable Pen, Universal Size Refill, 115mm/11.5cm/4.5 inches (Black, 115mm)

When I went to install it, it would not deploy. Then I compared the old and new and noticed the new refills are shorter than the originals. I had to make some adjustments for it to work... but then I noticed the INK FLOW was excessive. The ink covered the whole tip even when not in use which stained my shirt the very first day of use

Writes smooth and quite bold. Ink dries slowly and will smear if you are not careful.

Great pen refill for a standard pen.

Some are skipping. may be the cold weather

Used these in a couple different pens. Writes well. The ink does not last very long.

They are very practical, you may cut them to suit your length needs. Ink is hay quality.

While I can technically use them to fill my favorite pens. They’re not very good quality and leaks out on many of them. I’ll probably not reorder these again.

These gel refills really work well
