Charity wristbands are fast becoming the must-have accessory for members of the public and celebrities wanting to make an ethical statement.
White Make Poverty History wristbands, which were launched at the start of the year, have been seen on the wrists of celebrities including Davina McCall, Graham Norton and Jamelia.
This week CSV became the latest to follow the trend with the launch of a green band to mark the Year of the Volunteer. Paralympic gold medallist Dame Tanni Grey-Thompson was on hand to model them and support the cause.
The idea was initially inspired by yellow wristbands worn by six-time Tour de France winner Lance Armstrong.
Manufactured by sports giant Nike, the wristbands are imprinted with the words 'live strong' - a testimony to Armstrong's battle with testicular cancer.
They were a huge hit in the United States before filtering through to the UK, and more than 40 million have now been sold worldwide.
Now a growing number of charities are hoping to mirror his success with their own wristbands.
There are purple ones for the Cystic Fibrosis Trust, interlocking black and white ones for the Stand Up, Speak Up anti-racism campaign in football.
The Demlza House Children's Hospice is indicated by a red wristband, and drug addiction charity the Matthew Project is symbolised by black and red.
CSV's latest offering is emblazoned with the slogan 'What's your passion?'
Its wristbands cost £1 and are available at www.yearofthevolunteer.org.uk.
