They're decent quality and all, can't fault them for that. The only issue I've found is that the colours are far too dark, sometimes making it difficult to read any info on the disc through the plastic, particularly when it's a burned disc with handwriting for identification.
These sleeves are excellent quality and value, with the added bonus of having five different colours. They are lightweight but strong and fully protect the CD/DVD. Easy to use labels on and to slot in a play-list card.
