Staedtler Triplus 334 Fineliner 0.3mm Black – Box of 10

You need a line that's actually 0.3mm — not the smudgy 0.5 that blurs your circuit diagrams, annotations, or fine-scale maps. The Staedtler Triplus 334 in black gives you that super-fine metal-clad tip for controlled, precise strokes without the tip fraying after a page. Water-based ink lays down a clean, vibrant black that dries fast and doesn't ghost through paper. Ten pens per box keeps your desk or drafting table stocked without the single-pen run to the shop
