A packaging for two or more items includes a sleeve defining a first compartment configured to accommodate a first item. One or more ends of the sleeve is open or configured to be opened. The sleeve is formed by bringing together two longitudinal edge portions of a sheet and fixing the two longitudinal edge portions together. The packaging also includes a second compartment substantially external to the first compartment. The second compartment is configured to accommodate a second item and includes an opening that opens into the first compartment. The packaging may be associated with at least the first item and the second item so as to form an assembly.
