Thick outer vinyl sleeves


In the past I bought some sleeves that were 100% crystal clear and very thick: they can even stand straight on its own without a record inside.
Now I cant find them in the market... do you know where I can look for them?
thanks in advance

Are you talking about outer sleeves that cover the album jacket? Sleevecity.com has them (although I'm not sure they're as thick as you require):
