The lid opens up so you can save some of the balls for later. They have a yellowish tint and the smell of tropical fruit was strong as soon as I opened the box! The outside is supposed to be fruit-flavored chocolate, although I didn't taste any chocolate, only fruit. Inside the chocolate coating is a biscuit ball. Essentially, it's a smaller-sized Whoppers candy, with fruit flavor instead of chocolate. I'll have to find more chocolate-only versions to compare to what I remember about Whoppers.
The flavor is exactly as advertised - it tasted like I was eating tropical juice. You can see the mix should include banana, peache, pineapple, orange, and mango, These are pretty good, but I prefer my tropical fruit as an actual juice.
