Okay, here is my glittery Matau canister. I can confirm it was for the golden disc contest, with the following prizes:
1 Ultimate Gaming System
1 of 500 Golden Discs
1 of 50,000 Comic Collections
This info is from the side of the canister (sadly did not win any
)Also, this came with a Kanoka Card, which I probably lost as a kid
I now feel like getting all the different versions of the Metru canisters…
