Very low build quality internally and externally, it will not withstand the test of time. Internally, it has double-sided sleeves (each taking one disc in the front and one in the back), but they have a cutout that you have to remove the remaining cellophane yourself to create the entrance for the disc. This is difficult to do without tearing it due to the poor quality of the material.
Also, they are quite narrow and it is difficult to fit the discs inside. At least with the Blu-ray that I tried.
Overall, it is not worth its money, the ones we had 15 years ago were much better...
