The signed Liverpool FC shirt from the 2005 Champions League final is up for grabs in a Facebook competition.
James Hickman, managing director of Toolbox, said: "This is our first online competition using social media and we think that Facebook is the ideal platform to promote this because we can advertise the details directly to fans of Liverpool Football Club for a relatively low price, using Facebook ads."
Mark Satterley, financial and commercial director of Toolbox, said: "As a Liverpool fan myself it gives us great pleasure to offer something to our customers from a time that is cemented in Liverpool FC's magnificent history.
We are proud of our business here at Toolbox and it is exciting to be able to offer a prize that links our company with one of the most successful football teams in the world"
Plumbworld, an early pioneer of online trading was started by James and Anita Hickman in 1999 and sold to Grafton Group in December 2006. The business turns over £18m and claims a 20% annual growth rate.
