I did not buy a Stibila level but the case seemed like a good value and idea. My level fits great and it also had room [tight] for a 72" straight edge. I am sure it will stretch a bit with use. case is excellent quality. the trade tool store in my area wanted nearly $50 for the same case [crazy!]. You will not be disappointed. As others have commented we wish the zipper opening was a bit bigger/longer though.
