The appeal of a Jubbly was not the drink, but the packaging - it was a tetrahedron - 4 sided, and looked a bit like a pyramid. I must admit I didn't realise they were supposed to be drinks, as I only had them as ice lollys. You cut off one end of the package and ate the ice lolly by gradually pushing it out of the packaging, which was made from a sort of heavy waxed cardboard. Calypso in Wrexham are still producing them by the 1000s everyday. They're packaged in rectangular multi-boxes but are still the original tetrahedron shape.
