My only complaint about these books is that it is hard to bend the flaps of the sleeves back without damging or ripping the sleeves themselves.
It is not a major problem but the product offers resistance and the disc scratches against the folded-open flap.
If a person is already conscious of trying to protect the disc they are not holding the underside of the disc, so, you already have a disadvantage because you are not holding the disc in a way to make the movement any easier, and, it is hard to get your fingers to grab and lift the flap in order to fold it back.
