I use slimline cases for storing CDRs and DVDrs because they save space on the shelf, and these packs are ideal for use when purchasing the discs in boxes of 25.
I've bought cheap cases before but have never been that happy with them. These Imation ones cost only a fraction more but the quality seems so much better.
I'd never been a lover of coloured cases before but I love these because the colours are really nice, and I also think it's important that the fronts are clear.
I will definately be ordering more, and have no hesitation in recommending them.
