The Writech Clictek Liner works like a fineliner and opens like a ballpoint, with a click where the cap would be. It comes in six line widths from 0.05 to 0.5 mm, all with black pigment ink in a beige plastic barrel. When the tip retracts, an airtight seal closes over it, so the pen can travel in a bag or a pen loop without leaking or drying out.
Click it and start writing. The metal needle tip keeps the line fine and even, and the pigment ink is waterproof and resists fading and smearing once it is down, which makes it as dependable for fine lettering as for quick notes. Pick the width that suits the job, and the finest lines in your planner hold up for as long as you keep it.
