These are great little clips. The big ones work great for chip bags, the little ones are super for closing those bags of frozen veggies before you've eaten them all. They have no springs, they're one piece, they clip hard and strong and stay clipped, but are easy to use. What else can I say? I've had them for a year now and I love 'em!
UPDATE 2012: Well, friends, I love these things so much, I am back to buy more! 27 clips for cheap, what's not to like. Over the last 6 years, I've found so many uses for these, my drawer now is empty because they've all been "deployed" and are in-use. I need MORE! No regrets, only smiles, for these little gems.
