Outer sleeves protect! Protects from ring wear and everyday F ups, inner sleeves should be upgraded to plastic lined, you don't want paper rubbing wood pulp into the grooves.
When I get any new or used record, I immediately process them.... meaning a new Plastic outer sleeve, and a poly lined inner if it did not come with one.
I just started to buy the Mofi type inner plastic sleeves, I've been using the paper poly lined for the last few years and finally broke down for the rice paper type.
I'm just gonna use the new inners as new stuff comes in..
Here's Rocky Ericson and Nebula processed, and the Japan Press Black Sabbath came with a vintage Rice Paper sleeve.
