Reese’s Peanut Butter Cups
They have been around for nearly a century. And they are still very popular. That’s because they are very, very good. What’s not good is the package. It’s like they’re designed to ruin the experience. When you take off the wrapping paper, you take half of the peanut butter filling with it.

And you have paid for the whole thing. Of course, you can lick it off the paper, but that can (and always does) get messy. Not exactly convenient for work or school.
