Suntory and 7-Eleven have collaborated on a limited edition Boss Coffee only available through SEVEN&i Premium outlets, meaning 7-Eleven and Itoyokado. It is called 7 because it is a blend of coffee from seven different countries. It would be interesting to learn what benefit 7 varieties brings to the mix, but that is not detailed. There are regular (blue) and reduced sugar (red) versions.
