Laminated Toronto Map by Borch (English Edition)
Borch uses a patented lamination process to cross the folds of the map, making it easier to read and even easier to refold. The tough but non-toxic lamination material degrades to oxygen and water in a landfill environment. Before then, the map is practically indestructible in your backpack or suit coat pocket, and can even be written on temporarily with dry-erase markers.
