Good thing I decided to stay away from them! Was surprised to see my Three Blind Mice reissues from Impex to come in those as well. Poly lined paper is what I mostly use as well, sadly in some cases it makes for a very tight fit so I also use the Spincare's version of the Mofi sleeves: AUDIOPHILE 12 Inch Inner Vinyl Record Sleeves (Pack of 50) - For 12" LPs Never had any problems with surface scratches and I actually prefer them to the Mofi and QRP ones. The paper backing in those is slightly thicker so the corners don't bend around as easily. Makes it easier to get the record in and out of the outer sleeve. Also here in the UK they're around half the price of the Mofi's. The lack of any printing on the front of the sleeve is a good thing for me. As you showed with the Diskeeper 7" sleeves that ink stamp can migrate to the vinyl surface. And overall it looks better to me when you can see the full vinyl surface without any branding. I'll keep an eye out for any surface scratches (due to those sleeves) in future. The thing is if the record comes in a nice poly-lined inner sleeve I will usually leave it as is. The most common usage for those Spincare sleeves is records that came in paper inners and have very tight fitting (usually gatefolds) outer sleeves. My two Tone Poets that came in the RTI hazy inner sleeves are currently in Spincare's "Audiophile" inner sleeves so I will have to keep an eye and see if they develop any hairline scratches like other people have experienced from Mofi sleeves.
