You are doing nothing wrong. It is 2021 and the issue persists. I purchased the 312NRPS Diskeeper Audiophile 50 Inner Sleeves a year ago for my Titanic OST Black Vinyl. These vinyl discs were in Mint condition without a single scratch. Since I have been using these sleeves, I now have hairline surface scratches that only appear under a desk lamp. It is true, the audio is unaffected. But that is not the point. The point is these sleeves are not vinyl friendly. That silky look that these discs had are now ruined. I paid $85 for this sound track. They no longer press onto black vinyl. The purchase was from Germany. The question is, which brand sleeves have a good reputation? And, is it possible to remove these micro scratches? (question for webmaster) why is this site not setup to add an picture as an embedded attachment instead of providing a link for pictures?
