An entrepreneur has created a wristband that allows good deeds and charity work to be tracked all over the world.

Lachlan McWilliam, 35, has created the Band4Hope – a handmade copper and zinc wristband made by tribesmen in Zimbabwe.

Each band is inscribed with a hand-etched unique code which wearers register online, through which they can then track their good deeds.

Once a good deed has been done, the wearer then passes on that wristband to someone else, who then does the same – eventually mounting “a trail of hope” that criss-crosses the globe.

Mr McWilliam, of Withyham, near Crowborough, told how he was inspired by his wife Lucie, 31, after he went travelling through Africa, to move into social enterprising.

He said: “We wanted to do something for the world. We travelled all over southern Africa until we came across a tribe making the most beautiful bands.”

There are now Bands4Hope travelling in every continent – including three currently being worn by members of an expedition in Antarctica.

Mr McWilliam said: “Every wristband has a story and it our aim to spread hope by creating as many as possible.”

Celebrities have also endorsed the Band4Hope, with Annie Lennox, model Lily Cole, fashion designer Vivienne Westwood, Dougie from Temper Trap all spotted wearing them.

Each Band4Hope is made in Zimbabwe by ethically paid artisans using locally sourced copper.

Mrs McWilliam said: “It’s like sending out a modern-day message in a bottle that starts a ripple of hope.

"Who can tell where your Band4Hope will travel and what wonderful things will take root and grow? But as it does so, you can follow the positive impact of your one act online.”
