Query: Good case, sort of cheap, but it was cheap so...

For what you pay you really can't expect more from this case. Decent construction and materials, lots of loose threads but I just cut those off. Semi-rigid case that protects CD's and does just what a basic CD case should. The sleeves are riveted inside and feel firm and secure. I'm not sure I would call it "heavy duty" but it gets the job done.
