These maps are great for exploring Paris and France. You can unfold them to plan your trips, or fold them up easily to carry around. When using, be gentle to avoid further tearing. To maintain them, store in a dry place away from direct sunlight to prevent more yellowing. If they get dirty, you can use a soft, dry cloth to gently wipe the surface. And remember, although there's some writing on the maps, it won't affect your reading of the important information.
