Pilot V7 Cartridge System Liquid Ink Rollerball 0.7 mm tip Single Pen with 3 Refills - Blue

I enjoy these pens Write smooth with a 0.7 nib And I love the fact they use replaceable liquid cartridges Pilot is a great brand for gel refills as well I use and recommend them too

I like these very much. But two things: another reviewer noted the plastic pocket clips would likely break. They certainly do. I superglue a thin strip of plastic on top of the pocket clip, being sure it goes up to the top. The breaking point is at the bottom of the thin connection to the pen. Second point: are the cartridges no longer available separately? (As of 7/18/21). Is pilot phasing out this product? I cannot find black cartridges available separately.

This is a good roller ball, but you won’t find it in a bus supply store
