Staedtler 3187 TB18 felt tip pens comprise an 18-piece set featuring assorted colours, designated under the manufacturer's part number 2588545. Designed for precision and vibrant colour output, these pens utilise a fine fibre tip capable of creating lines with consistent thickness and clarity, making them suitable for detailed drawing, drafting, and colour-coding tasks. The water-based ink is formulated to ensure minimal bleed-through on most paper types, which is advantageous in technical documentation and annotation of engineering blueprints. With a robust construction to resist drying out, these pens are ideal for use in environments where consistent, reliable marking is necessary for professional presentations and record-keeping. https://elecena.pl/product/29568408/staedtler-3187-tb18-felt-tip-pens-18-pieces-assorted-colours 2025-12-05 https://elecena.pl/product/29568408/staedtler-3187-tb18-felt-tip-pens-18-pieces-assorted-colours 2026-07-02
