Scarlett Johansson is stepping up her charity efforts for Haiti - she's designed an exclusive handbag to raise money for the earthquake-devastated nation.

The tote is emblazoned with an ancient map of the Caribbean country, with the message 'Supporting the people of Haiti' written and signed by the Lost in Translation star.

It will be available through Mango fashion stores across the world, with all profits benefiting Oxfam's relief fund for the region, which was hit by a massive tremor last month (12Jan10).

Johansson says, "I'm thrilled to be collaborating with Mango to promote conscious consumerism and to benefit Oxfam's Haiti Earthquake Response Fund. By purchasing this bag, which I specially designed, you are helping to provide life saving assistance like clean water to the people of Haiti."

The actress last month (Jan10) auctioned an evening of her company to four fans to help benefit the relief effort.
