Ballsign iD is the name for a series of ballpoint pens that use a water-based gel ink. What is special about these pens is the guiding principle of “six colours of black”. Users can choose their favourite from six refills in different shades of black. The body of the pen is pleasant to hold as its shape is a combination of a circle and a hexagon, something which gives it stability. The metal clip with the company logo radiates quality and rounds off the design concept.
