What a Club is: A chocolate-covered biscuit bar in a foil wrapper, thicker-coated than most British biscuit bars. The slogan - "If you like a lot of chocolate on your biscuit, join our Club" - is one of the best-known in British advertising.
Mint: Mint-flavoured chocolate over the biscuit, the version that splits opinion most sharply in the range.
Seven to a pack: Individually wrapped, so it is the lunchbox and desk-drawer format rather than a sharing biscuit.
