That one grey marker you keep reaching for — the one that doesn't ghost after a week or feel slick and useless by paragraph three. The Artline Supreme Permanent Marker (Fine 0.4mm, Grey) gives you a crisp, permanent line on paper and board with a glossy grip that actually stays put in your hand. The body is built with a silver-based antimicrobial coating, so when it's passed around a shared desk or a staffroom, surface bacteria get a hard time taking hold. It's one of 15 colours in the Supreme range, and you can swap to Bullet or Chisel nibs if a job needs a heavier hand. Grey, fine, done
