These are pretty good, and they don't make my fingers indelibly orange. It says real cheese, and low moisture mozzarella cheese is listed in the ingredients, as well as "granular cheese". In addition to the mozzarella flavor, there's also some garlic and pepper flavoring.
It looks like the food companies have decided they can't shrink the packaging any more because people have noticed, so they're raising prices again. This is the first 4 oz. bag I've seen go up to $1.29 from 99 cents. It does look like they increased the size of the bag a little first before raising the price, to give the illusion of getting more for the money.
