This is substantially better quality than I had hoped for! I have tried various folders for sheet music and these are definitely the best. The sleeves that hold the pages are strong, not the flimsy polythene that you usually get. The spiral that holds the pages is not the type that gets twisted and unravels! The whole thing opens out flat which is perfect. There truly isn't any aspect of this folder that isn't right. This is why it is expensive! The whole thing is fairly heavy, so if you don't need to have 30 or 25 sleeves, there are versions with 15 or 20 sleeves.
