These clips are excellent.  They won't change your life, but they're extremely handy.  They are quite well-made.  They last, and they maintain a tight grip rather than losing their "spring" after repeated use.  Also, the relatively wide and flat surface on the business end does a better job than most alternatives at holding closed a wide-mouthed bag of pretzels, chips, etc.  The bright colors are also attractive, and the fact that they double as refrigerator magnets is a nice twist.
