This set of X-Acto knives and blades has a convenient selection.  The zippered, ballistic nylon is oddly large.  The shaped, plastic insert that holds the knives creates a lot of extra space that can't be used.  The magnets for the knife blades are quite weak.  I'm not in love with the case.  It is marginally functional.  Fortunately, I selected this set for the contents, not the case.
