I bought these sleeves as we seemed to have loads of CDs with no covers or cases of any fashion and I wanted a cheap option to keeping them clean and relatively safe.
Upon researching the products available I settled upon these as being the cheapest option available that would do the job - as I had SO many CDs in need of a new home I didnt want to spend any more than I had to re-housing them, most of them weren't worth the extra expense (home recorded/backup discs etc). To be truthful I wasn't expecting much from these sleeves for the price I paid for them, believing them to probably be of an inferior material and flimsy, thin construction, but I was pleasantly surprised when they arrived, they were of a pleasing consistency and sturdy enough to provide a modicum of protection to discs that are "thrown about" in storage and generally filed all over the place!
Don't get me wrong, they're no substitute for a proper CD case but as a budget option, they are an excellent solution - so much so I went back and ordered another packet of them from the same seller a short while afterwards! I've had up to FOUR CDs in a sleeve without any problems or tearing at all and never had any trouble with bunching or sticking like some other reviewers reported - they're DEFINITELY large enough to hold CDs and DVDs - I don't know where those comments came from about size inadequacy!!?, all in all an excellent budget product and HIGHLY RECOMMENDED! :-)
