STAEDTLER triplus fineliner 334 — Box of 6 Assorted Colours
6 coloursapprox. 0.3 mmTriangular barrelDRY SAFE
The STAEDTLER triplus fineliner 334 C6 is a cardboard box with six triangular fineliners in assorted colours, with a superfine metal-clad tip writing approx. 0.3 mm lines, for note-taking, planners, bullet journals, diagrams and colour-coded notes.
The ergonomic triangular barrel sits comfortably between the fingers for long writing sessions. STAEDTLER's DRY SAFE feature means the pens can be left uncapped for days without drying out (except neon colours). The ink is water-based and washes out of most textiles, and the housing is made of 97% recycled plastic, made in Germany.
Before you order: STAEDTLER does not list the six colours for this box. Water-based fineliner ink is for paper: it is not permanent on plastic, glass or film, and it is not document-proof.
