Source & specs for LP poly outer bags


I know of uline.com, but anyone have other sources for poly bags for LP jackets.

Are bags good, even?

Preferred thickness? 5mil ? 3 mil ?

Do any of you also bag box sets?

Thanks in advance.

I'm told they're effective at protecting the album covers from showing circular disk wear.
