Montblanc introduced the SL (slimline) 2 colour ballpoint in 1981. The original pens, this example, were stamped 'Germany', in 1985 the stamp was changed to 'W.Germany'.
The pen, constructed in stainless steel, is in excellent condition with a small scratch on the clip snowflake, easily rectified by a very steady hand. The heavily chromed clip has a first class finish.
The two colours, at the moment black and blue, are accesssed by turning the cap to the right for black ant to the left for blue. The refills are both working and are also available online in a range of colours.
At over forty years old, this is a top quality ballpoint. The mechanism is smooth and efficient and the avaiability of two colours could be very useful in a range of situations. It is an attractive, practical and robust pen from one of the world's best pen makers.
