Review on Memorex CD/DVD Keepers - 📀 Plastic Sleeves: 50 Pack for Organized Storage by Matthew Thorndike

I've put over 60 games in these cases. I needed space so I took my "new" games out of their sleeves/paper sleeves and put them in these plastic sleeves that kept upright in the shoe box. .Recently I pulled out some games to download to my computer and noticed something like "stuff" on my drives? Over 90% of my games are new so I was confused. I had to use hot water + microfiber. Towel to wipe off dirt. Well, getting to the point, I pulled out a few more and saw the same thing: big blobs of "stuff" on some discs. Since my games are new and the manufacturers are different, I was at a loss. I cleaned that too. To see what's what, I pulled out a game I cleaned up a while back; yes, screwed up again. It seems that these plastic sleeves do not breathe and the sleeves, like a master, transfer some kind of garbage to the discs. I'm talking rubbish because I had to clean it = it got dirty with a regular cotton rag. After extracting over 60 games (over 120 drives), we counted 78 drives that needed cleaning. Be those sleeves. Some were easy to clean, others required a little pressure to remove dirt/substance. Trust me I am very careful with my games! I would buy this or any other plastic case with caution.
