Staedtler Triplus Colour fineliners are high quality fineliner pens with vibrant metal-clad tips. Each pen has an ergonomic triangular barrel for relaxed and easy writing. The water-based ink washes out of most textiles and the pens are airplane-safe as the automatic pressure equalisation prevents the pens from leaking onboard aircraft.
The ink is also dry safe, which means that the pens can be left uncapped for days without drying up. There are 20 vibrant colours available, each with a line width of approximately 0.3mm. An ideal tool for colouring, crafts and illustration.
