When only one country is responsible for over 50% of the world´s production in anything, it is a cause for national pride. When that country has an area of around ninety thousand square metres and a population of ten million, then the achievement is even more noteworthy. Perhaps that is why we have seen a trend in Portugal for a number of fashion accessory initiatives using cork. INA KOELLN (a German designer based in Lisbon) is the most interesting of all those I have encountered. The Walt is a supple cork rucksack with adjustable leather straps, cotton lining and an inner pocket for a laptop. And, as with all models in the brand, you can choose from two shades: dark or light brown. There are lots of backpacks. Good-looking cork rucksacks are few and far between
