Coloured pencils based on paraffin waxes and paraffin oils. They write excellently on almost all surfaces, are colourfast, temperature-stable, smudge-proof and break-proof.

Type 218P (mm) with 20 metre length.
The rolling tape measure consists of parallel glass silk threads embedded in plastic.
The graduation on the yellow tape is black and the numbering is black/red, which ensures good optical legibility.
