If TROIKA’s most successful products (the pens in the Construction family) enter into a partnership of convenience with its most successful product group (keyrings), then the result can only be something quite unique That was the thinking of one of TROIKA’s members of staff, who then set the ball rolling and mentally designed the new MICRO CONSTRUCTION. Using this idea the in-house TROIKA Design Werkstatt (design workshop) created the delicate ballpoint pen and keyring. This compact product (21 g!) packs quite a punch: for analogue and digital use (ballpoint pen and stylus), it includes a centimetre and inch ruler plus a slotted and Phillips screwdriver that are ideal for solving minor everyday problems. And quite by the by, the strong ring that is attached to the end of this multi-talent, makes an excellent keyring. MICRO CONSTRUCTION is available in six elegant trend colours.
