When I lived in the US, my best friend and I used to buy them from the candy store at the mall all the time. I even remember bringing them to school with me a few times. I loved Dr. Pepper, buttered popcorn, cappuccino, caramel apple, peach, top banana, and a few others. I didn’t like the bubblegum or cotton candy (too sweet), and I wasn’t crazy about licorice, either.
I think I saw them at a grocery store in my town once, but they are pretty expensive like all foreign products.
