I use them to display jewelry in my store to close chip bags and cracker packages to attach vines in my garden to trellises to leaves notes for my family and dozens of quick needs!I recommend them as a staple in your rubber band drawer.
This page would not allow me enough characters in the pros and cons so I'll say it here. We use these clips every day! We clip packages closed with them: chips cereal crackers etc. My husband's favorite use however is to hook the outdoor Christmas lights to the roof shingle edges and gutters with them. They clip on tighter than the regular plastic clips and they don't blow off or out of place in the wind. They have been a part of our Christmas decorating for years.
