I used to buy them from Big W, and remember them being available many years before this from other stores.
They were like a boiled lolly (aka bonbon?), each came in a single colour, but there were different colours/flavours mixed in the bag.
There was a word embossed into the front (& possibly back) surface of each. Paper wrapping. Photo
Pascal Bon Bons, IIRC.
