The Staedtler pigment liner is a high quality fine liner for writing, sketching and drawing. This 0.2mm pigment liner gives a clean, smooth and precise line with archival-quality ink. The black ink in these pens is permanent and water resistant. The 0.1 pigment liner pen is designed with a long metal tip, making it ideal for use with rulers and templates. The pigment ink is indelible (in accordance with ISO test 14145-2), lightfast, waterproof and is also erasable when used on tracing paper and does not bleed when it`s highlighted. The pens have an 18 hour `cap off` period which means the pen can be left uncapped for up to 18 hours without drying up (ISO test 554). The pen is airplane-safe and the automatic pressure equalization prevents the pens from leaking on board aircraft. The pens are made from high-quality, durable plastic, with a fineliner tip. Several different nib widths are available to choose from, in sizes 0.05mm to 1.2mm, to suit your needs and preferences. - Brand: Staedtler - Colour: Black - Main material: Plastic - Permanence: Archival quality permanence - Tip type: Fineliner - Water resistant: Yes - Nib width: 0.2mm
