This ergonomically designed Staedtler Triplus Fineliner features a triangular barrel for comfortable writing and a metal-clad tip for durability. The water-based ink washes out of most textiles and is dry safe to allow the pen to be left uncapped for 2 days. The fine 0.6mm tip writes a 0.3mm line width for precise, controlled note-taking. This pack contains 10 black pens.
