The LAMY ST Tri-Pen in Black packs three writing tools into one slim body – two ballpoint colours and a 0.5mm mechanical pencil, all in one design by Gerd A. Müller.
A simple twist of the barrel switches between functions: align the marked label with the pen’s clip to extend a black ballpoint, a red ballpoint, or the 0.5mm pencil. A discreet eraser is hidden beneath the push-button cap for quick corrections. Finished in a matt black lacquer over a stainless steel body, the Tri-Pen is a genuinely useful everyday companion for notes, colour-coding and quick sketches alike.
