Sour Wildberry Skittles. I created my own custom sour concoction. It's my secret so you just have to trust me they are sour and these are my personal favorite (and I really don't like sour) They start out super sour, but the after taste of the wildberry, is so satisfying. It's like pain then pleasure. These bags are as full as I can possibly get them, so you will get a great value.
