One category above the cheap ones available in the market. Size is okay. It doesn't easily fit thick gate fold covers. They are blurry but their quality is good.

The plastic is semi-transparent. Not exactly what one would expect for the covers of the discs

Good in terms of size, they come as they should.
However, be aware that they are blurry. If there are any damages on the cover, they are somewhat hidden due to the blurriness. But if the cover is in good condition, the blurry case reduces it.
