Just got back from Asda in Aberdeen and thought this was a pretty decent deal:
The Parker Slinger II ballpoint is a retractable pen for people who lose pens! It has a convenient bullet design with clip-on nylon landyard. Ideal for office, factory or outdoor use, the Slinger II has a distinctive chrome barrel, rubber grip and coloured clip available in 3 different colourways. Supplied with black fill as standard but takes standard Parker ballpoint refills.
They had quite a few in stock, in different colours
