I love these Big Rubber Bands...with all the files I have for my family tree records and notes these bands allow me to keep all the data that I need to keep seperate just that...Seperate! even when the items are stored in the file cabinet...no more small notes falling out of the file itself. I also use these big bands to keep my office files together. I use them throughout my house to keep almost anything together even to keep the plastic bag inside my waste basket from falling down when I put the band around the outside holding the plastic bag secure to the basket. Thank for this very important item! It makes my life calmer.
