Commonly referred to as Chip Clips, this kitchen tool is made to clamp around the opening of a bag of crackers, chips or other foods to help keep out air and moisture to keep the product fresher. Made of plastic, wood, or metal, Snack Clips are designed in a variety of shapes and sizes some fitting only smaller sized bags while others are up to 6 inches in length so longer bags of food can be closed using a longer length clip. In addition to different sizes, some Snack Clips also have magnets built into the clip so they can be attached to metal surfaces to hold not only bags but also sheets of papers for use in displaying notes or instructions.
