ZEBRAJK-Refll G301 Retractable Ballpoint Pen Refills, 0.7mm, Medium Point, Blue Ink, 6 Count (3packs x 2 refills each)

What can I say? They write smooth. The only draw back is that you will burn through the ink but that's expected from a bold gel

These are the best pens! I carry a box with me to hand out because my coworkers threaten to steal them from me.

Luv these to be able to refill great pens that I use every day at work to be able to write clear and precise paperwork

It may be my imagination but the refills seem to empty quicker than the full store bought pen. It still writes incredibly well

Excelente

This is the only pen I use. So thankful for these long lasting refills. Good value for the money and they consistently perform.

Terrific

You just be attention on number you want like 305g or f and when its done you will enjoy by writing smoothly
