Before I bought these clips I used generic blue clippers that were given to me as a promotion for AARP.  I didn't know there was a commercial product I could buy to close bags and anything else I needed closed.  Well I saw these at the supermarket and bought them to see if they worked.  NOT only do they work they work marvelously well!  I love that they have magnets on them so I am never looking for them in my kitchen drawer.  They hold fast and never let go.  I am buying five sets today from Amazon for less than the supermarket charges and their in pretty colors to boot.  The ones I bought previously were only in white.  These work so well to close bags within their boxes like cracker and cereal bags. I am giving a set to each of my daughters and daughter in laws.
