The cases are ansich of handling is not bad, because a little thicker and stiffer than the legendary Nagaoka 102. Here they are in order to put them in the verhandene (printed) paper sleeve, as opposed to on the packaging usually too large. The inner shell undulates then within the paper wrapper. Therefore, I will bite the bullet and buy a pack additionally overpriced Nagaoka. For replacement of a simple, plates scratching paper sleeve this inner linings are of course well suited.
