Outer Vinyl Sleeves, is it a good idea?

Yes I remember back in the 70s a magazine I was reading said..remove the plastic outer sleeves from your records they will couse record warping...So I did .all of those albums were sold back in 2015...little did I know,it was my mistake. I sold 1100 records for 1,400 bucks...the guy who pick these up for the record store I sold them to ,said...hey can I ,come over before they are packed up and buy some for myself I will give you 5 dollars each...he bought 20...I should of known...mine were well cared for .I was cleaning albums when Hardy anyone did it...Well I bought albums again but now I bought ,other people's collections cheap..I know gave about 1500...all with new paper sleeves...yes paper and plastic heavier gage  outer sleeves and yes the records are kept on the out side of the record sleeves..Yes that German guy on YouTube has beautiful audio equipment and knows his stuff.

- Plastic seal goes off

- Vinyl sleeve goes on

most of the time: I’m not too scrupulous about this.

I have 6,000+ LPs. 

Mold?
Perhaps it’s from moisture build up from excess perspiration caused by the dancing audiophile 😉

Speaking of inner sleeves, Mo-Fi inner/outer sleeves are back-ordered at most online vendors. So I decided to try Hudson Hi-Fi Anti-Static Vinyl Record Inner Sleeves (250 pack for $49.95). And they are just as good as Mo-Fi and cheaper which means I’m done with MoFi inner sleeves.
