The flavours are (followed by wrapping colour): Malt (Blue), Harrogate (Yellow), Mint (Green), Egg & Cream (Orange), Coconut (Pink), and Toffee (Maroon).

The product's subtitle is "Toffee De Luxe" and its motto is "a tradition worth sharing".

[3] Unlike the British versions, it was a hard candy which, for most of its history, was sold as a single rectangular bar in a tartan box.

Recently (2013) Nestlé Canada has been distributing an apparent recreation of the hard Mack bar, though thinner and wrapped in foil.

Nestlé does not distribute the toffees in the US, but it may be ordered online for delivery or found in specialty candy shops.
