Based on the reviews here I bought two of these cases (one of each size). They arrived a few days ago and now serve their purpose of storing/protecting my best filters by always having them handy. As mentioned, the quality of these cases is excellent. They aren't rigid so they won't keep the filters from breaking, but they do protect them from scratches. (It's my job to avoid breakage.) It's easy to tell one size apart, allowing me to reach into my bag and pull out the exact lenses I need. I am very satisfied with these filter bags.
