Created by David Weeks, a designer known for high-end modern light fixtures, Animal Farm chip clips are intended to give one pause while grazing in the kitchen. It came from a kind of humor,Mr. Weeks said. Is this chip clip judging me as I eat more and more potato chips?

The clips come in a set of three animal heads, with strong, spring-loaded jaws for biting onto open bags and integrated magnets that allow them to be attached to the refrigerator.

Mr. Weeks said he selected the animals depicted a pig, cow and goat with care. They are livestock, but they are also the greediest of the farm animals.
