I love sour things but this thing is too much. When you suck this candy your mouth aches though after a while it returns normal but at the verge of finishing this toffee some salts come out of it which tastes bad and even more sour and salty.
If you eat 2 of these one after another you have to suffer from tongue ulcers because these are very poorly built and thus it’s corners are very sharp and cut your tongue.
