摘要

The refill is for multi coloured ball pens. It consists of a refill pipe with a writing point fixed in it. The writing ball point (20) is inserted in an intermediate piece (22) made from plastics homogenously coloured to correspond with the ink colour of the refill. The intermediate piece (22) is fixed inside the refill pipe (10). The intermediate piece (20) together with the ball point have the same measurement as a writing point made from metal. The refill pipe may be made either from metal or plastics material.
