Product review (4 stars): I use these in my bookcase to get rid of those "leaners"
I like to use these in my bookcases and pantry like book ends.  They are easily repositioned and are unobtrusive.  I have a lot of packets of seasoning and gravy type mixes in the pantry and I can line them up and put one of these bars at the end to keep the packages fro slipping and sliding all over the place.  My bookcase looks neat and keeps books from becoming "leaners".  There are a wide variety of DIY projects you can use this style of short bars for.  I love them.  This brand is well constructed and stays in the position you put it in.
