What was this "gravel gum candy" product from the early 1990s?

This is such a massive long-shot, but it's been eating me up for decades now. I need to at least try.

In the early 1990s, my brother and I used to walk to this local little grocery store (long gone) to buy these small Tetra Pak-contained little "gravel chewing gum" candy products.

I do not remember anything about the name, the logo, or even the illustration of the package, besides a vague memory of bright green, blue and pink shapes. I do, however, vividly remember what the actual product inside looked like. It was chewing gum of some sort, shaped like gravel (little blue rocks) of slightly varying sizes.

It is extremely unlikely that it was made exclusively for/by/in Sweden; this is almost guaranteed to be some sort of bulk-imported product from "somewhere in Europe" or indeed "somewhere in the world". I'm somewhat confident that the text/title on the product was in English, or at least not Swedish. I probably would have remembered it if it had been in Swedish, and I have never heard anyone mention this product or seen it for sale in any other store, even back in the day. I would know it instantly if I saw a photo of it.

I have created a little illustration which represents 100% of everything I remember visually about the package and the product inside.

Can anyone please identify this product for me? I would be very surprised to learn that it's actually still sold, because all such nice things from my childhood seem to have just disappeared long ago, but even just knowing the name and perhaps being able to find a photo of it would stir up such nostalgic feelings that it would almost be enough.

And if it's actually still sold, somewhere, well, then I'm going to order a few at any cost, even if they have likely changed to a "new improved recipe" several times during these years...
