Hi Todd
All the global supply of cheapie plastic inner sleeves are made in Japan by Nagoaka?

see link below for an example of the cheapies.

Very interesting fact that these woven sleeves are made from poly/plastic. I thought from the photos they were made from some woven cloth like material. If this being the case, I sincerely take back my statements about woven material breaking down.
I guess the woven plastic is fine enough that it does not micro scratch the vinyl when pulling the lp in and out? To me, I can't see how it can be as smooth and non evasive as normal poly inners but what do I know
That said, I can't see how ther can be any difference in performance of the cheap poly inners and any other more expensive plastic based inners in protecting our precious vinyl.
All the best and thanks for clarifying the material these woven inners are made from.
