First-class cases. I have these cases brought to my complete Blu-ray collection, unbeatable at the competitive price of the equivalent of about 5-6 cents per envelope. With me every Blu-Ray comes, whether Amaray Case or Steelbook in these cases. So you have protected the collection from dust and scratches. After watching the Blu-Ray wanders back into the sleeve. The cases are to use more than once. So you can watch the film and then stow the Blu-Ray back in the envelope and glue. Even if you should change the bag that will not hurt you at the low price. The shell is crystal clear and perfectly fits, the collection is not so visually impaired.
