An elongate blank for forming a sleeve includes a plurality of panels. The panels include two rear panels. When the blank is folded to form the sleeve, an outer rear panel overlies an inner rear panel and a pocket is formed between these panels. The pocket is configured to contain one or more objects. The sleeve is adapted to be placed on a container, such as a package containing smoking articles. The pocket can contain another tobacco product, such as one or more promotional smokeless tobacco products.
