British rocker Sting and his wife Trudie Styler have launched a line of bags made out of elephant excrement to raise funds for a charity in India.

The couple celebrated the launch of the recycled bags on Monday in London in conjunction with The Big Issue publication.

On one side, the collectable items have the words The Bag Issue printed on them, while the United Nations' Universal Declaration of Human Rights is printed on the reverse.

Styler tells Britain's Daily Mail, "We have been using elephant dung to make collectable bags to be sold in aid of the Mukti charity in India. It sounds pongy (smelly), but it doesn't smell."

Funds from the sale of the bags, which are made by local Indian women, will help disadvantaged children at the country's Karm Marg orphanage.

Sting flew into the U.K. especially to support his wife at the launch and was exhausted from travelling.

He says, "I've just flown back from my last night of a world tour to be here for my wife. I'm utterly exhausted - all I've done today is sleep."
