I had looked everywhere for corner shelves that would provide a clean and uncluttered look.  I ordered 8 of these to frame some art work.  After making the first set of holes in the wall, I knew we were doomed.  The shelves did not give any support on the other side of where the supports were and sagged horribly.  We were committed at this point due to the large holes you make.  We did not want braces, so was left to try and salvage what we could.  We ended up getting backsplash tiles and separating them to make a pattern for support under the shelves and using glue to secure the tiles.  I am not happy with the look, but it is what it is.  If you can, keep looking as these shelves do not provide support for anything on their own and in fact will not even hang straight without anything on them.  Very disappointed!  (Has a one star rating just because it won't let me not put anything).
