For those who spend a lot of time writing or drawing, a comfortable writing feel is especially important.

For this reason, the STAEDTLER triplus ball has an ergonomic triangular barrel that relaxes strain on the hand and offers excellent writing comfort.

Our STAEDTLER triplus ball's airplane-safe feature provides an automatic pressure equalisation which prevents the pen from leakage while you are on the plane.

STAEDTLER's ballpoint pens with indelible ink corresponding to ISO 12757-2 are lightfast, waterproof, chemical and solvent-resistant, smudgeproof and non-erasable.

This means this pen is ideal for use on cheques, documents and contracts.
