The Staedtler triplus fineliner has an ergonomic triangular shape for relaxed and easy writing and colouring. The fineliner is dry safe which means it can be left uncapped for days without drying up. The water-based ink washes out of many textiles. It has a fine metal-clad tip and a linewidth of approximately 0.3 mm. The fineliner range is available in 48 brilliant colours.
