Each PENTONIC featherweight pen has a sleek finish for a comfortable grip and smooth, effortless writing and journaling. The nickel silver pen tip is 0.7 mm fine point for thin, precise lines. The low viscosity ink allows the rolling ball to glide across all kinds of paper surfaces without smearing. You get a consistent flow of ink from the very first use to the very last. The pen cap also helps to maintain the lifespan of your ballpoint pens!
