Why You’ll Reach for It

Small writing disappears when you are labelling a box, marking a project, or making a sign. The 3.8 mm tip creates a strong, readable mark that is easy to spot, while the oil-based waterproof ink helps your writing stay useful when the surface or environment gets less forgiving. When the ink runs low, the refillable design gives the marker another working life.
