All of Staedler’s Triplus range are supremely comfortable to use, and these fibre-tip pens are no exception. Their triangular barrels are ergonomically designed to ensure many hours of fatigue-free writing or drawing. The ink is water-based and easy to wash out of most textiles, and it’s also dry-safe so the pen won’t dry out, even if you leave the cap off for several days. The 1mm fibre tips are sturdy and pressure-resistant. This Staedtler Triplus Fibre Desktop box set contains a range of 20 assorted colours.
