There aren’t any
The box of snack-size zip-lock bags I got has on it a picture of some pretzels, as an example of appropriate use probably. “Buy these little bags and you can take pretzels to work with you.” Maybe studies show people are more likely to buy the bags if there’s a picture of iconic snack food. But every time I see the box I experience a brief flash of happy expectation, then disappointment. “Oh, pretzels! No, just those darn bags again.” I’m thinking I could put the little zip-lock bags in a quart zip-lock bag, then I wouldn’t be reminded of pretzels all the time. Plus, then I could take the snack bags through airport security.
