Pen Ink Refills

Available9 products

Pen ink refills can be used with compatible pen barrels to extend service life. Ballpoint refills feature quick-drying, oil-based inks. Gel and rollerball refills distribute water-based or gel-based inks that are less viscous than ballpoint inks, with smoother and bolder performance. Metal-detectable refills can be detected if lost to prevent contamination of products in food processing and pharmaceutical manufacturing facilities. All-weather refills are capable of writing in wet and oily conditions, such as outdoor environments and manufacturing facilities.
