Never set out to look with an obsessive critical eye, but today an overhead can light in our living room, caught an album just right as I was flipping sides, and I noticed some very faint little marks on the album. Under other lighting, you can't see these tiny marks. I tend to use plastic anti-static sleeves by Diskeepers or a few from Quality Record Pressings, touted as non-scratching, but seems they do (faintly). Guessing removing and putting back the albums will cause this no matter what kind of sleeve used? I don't use paper sleeves. Any other sleeve recommendations, brand, etc? Or, guessing just the nature of the vinyl surface itself. Thanks.
