This company is from Greece, so these are probably easy to find in South East Europe, but I heard people from Sweden and Australia talk about it...
Anyway, I have tried three of those, plain one, smoked and the one with the olives. They're pretty decent, especially one with the olives, as I could stand to eat it alone. other two are pretty good melted. Regarding the ingredients, there is no casein or derivations, just a bunch of modified starches

, so not that this is necessary in your everyday diet

In my 15 years, I have tried these fake cheese just like a couple of times, otherwise, if they were available here, probably wouldn't pay much attention
Something more than ink.... On a page, on a shirt, on the back of my hand.
