Dime/Daim available much earlier than 1980's.
NLCSGRV,
Nope !!!
They were available early 70's at least and had a completely different name.
Remember that they were for sale in my local Newpaper Shop / Corner Shop [UK] somewhat North of Watford :).
[Might even had been branded as another company other than Marabou. i.e. licensed to someone else !!!???]
Cannot remember the name but they disappeared for a few years then came back as 'Dime' Bars.
They then got re-branded to 'Daim' probably to make production/distribution cheaper as they could be made with 1 wrapper/name and shipped to whichever country needed the stock.
