Product Information

Full details

This guide is for anyone who wants to use the Uni-Ball Signo UM-120SP Metallic gel rollerball pens. These pens are perfect for adding a metallic sheen to your writing and artwork on both light and dark paper. A key benefit is the waterproof and fade-proof pigment ink, ensuring your work lasts. However, note that the 0.8mm tip creates a 0.5mm line, so fine details require a steady hand. This guide provides essential information on using these pens effectively.
