Record Sleeves - Which ones and where?


I'm looking to replace all of my record sleeves with better ones. I've seen polyethylene, polypropylene, and rice paper lined. What's the difference? I'm looking for the best place to buy them too. Is it worth getting outer sleeves too? Please advise. Thanks!

whatever you do stay away from Sleeve City.

2 sets of different sleeves in different shipments came in bent up.

They offered to let me return them, but between shipping

and my time it wasn't worth it. They would not reiumburse me for return shipping so they wont be getting my business any more.
Spenceroo,
What I have always done, and I'm sure all will agree with my practices, is that any plain jane inner paper sleeves with no writing on them, or the ones that may show just other releases by the manufacturer (EMI-Capitol, RCA-etc) I usually dump as quickly as possible.

Those that have Pictures, and/or Lyrics, and information about the particular release, definitely do keep them, and in general, I have usually found ample room to place these inside the LP Jacket with the LP, and new Inner Sleeve without too much crowding, or difficulty getting the LP in, and out.

If you should personally find a release, in which it is just too tight a fit to fit both Inner Sleeves, then yes, place the saved original inner Sleeve outside the Jacket, and place at the rear of the Jacket within the Outer Sleeve for protection, and safe keeping for future reference.

Hope this helps. Mark
Thanks guys. Very interesting. Now I have about 800 outer sleeves to buy. Sheesh. When does it ever end. I've been buying a ton of inner sleeves since I got a used Nitty Gritty Record Doctor a few months ago, which I absolutely love, by the way (brought a whole new clean experience to my vinyl). I had never really thought about outer sleeves. You're right, with just inner sleeves, its like only doing half the job.
Thanks again Mark for your precise help. I'm going to call Music Direct and inquire about the 6 mil outer sleeves as well as inners. Do you really need inner sleeves if you put the whole album, cover and all, in an outer sleeve? I'm suspecting that the old paper sleeves flake and whatnot onto the vinyl making them dirty correct? Is there a difference between polypropylene and polyethylene sleeves? I've seen both for about the same price.
