The pens of the Troika Construction family were combined with the company’s key holders to create this delicate ballpoint pen plus key holder. The compact product weighs 21 grams, is suitable for analogue as well as digital use as a stylus, and helps solve minor everyday problems through a ruler in centimetres and inches in addition to a flat- and Phillips-head screwdriver. The Micro Construction with its strong key holder ring is available in six elegant and trendy colours.
