20 triplus fineliners supplied with a magic zip pencil case. The pencil case is a 2 m long zip that is formed by closing the zip all the way round. Staedtler triplus fineliners are high quality fineliners with superfine metal-clad tips. The pens have an ergonomic triangular barrel for relaxed and easy writing. The water-based ink washes out of most textiles, the pens are airplane-safe and the automatic pressure equalization prevents the pens from leaking on board aircraft.
