Astrid Aichner-Rigo and Josef Rigo from 1985-1987 were development aid workers in Tanzania.
After her return, they tried to found a fair trade shop. With the material and moral support of the Third World Group Brunico and the Weltladen Sand in Taufers, in 1991 they called into being the association "Third World Shop Twigga St. Lorenzen".

In 1993, the opening of a small shop in St. Lorenzen followed. On the shop sign, the association wrote its name "Twigga", which means Giraffe. The long neck of the giraffe symbolizes the looking beyond the own borders and interests, and openness to the beauty and problems of the world.
