Stationery and paper goods company Nancy & Betty have just launched its collection for 2013, and among the new items in the line is this precocious tape, emblazoned with the word Supercalifragilisticexpialidocious. The biggest word you've ever heard is the perfect silly message for when, well, no other word will do. (Oh, and if you just have to listen to the song, here's the clip from Marry Poppins. My apologies for getting it stuck in your head.) Supercalifragilisticexpialidocious sticky tape, £5.95, Nancy & Betty.
