Vintage Card Sleeves clarity question

[4k6]

Is it possible to find "Crystal Clear" vintage card sleeves for 52-56 Topps cards?

I use the toploader/soft sleeve storage method. Ultra-Pro Premium Card Sleeves for standard sized cards are described as "Crystal Clear", and they are. I can only find Ultra-Pro Vintage Card Sleeves in "Clear Polypropylene", difference being that they aren't really clear, sorta foggy. It bothers me and I can't find any other vintage sized soft sleeves. Suggestions?

And hello. I'm new here, wierd first post question.

I've always been under the impression that the clearest storage material is archival quality mylar film. Lower grades of plastic, like polypropylene and others, will tend to have some opacity, however slight. I believe you can find mylar sleeves in the size you need just about anywhere on the web - just check to see if it's archival quality.

I just use Card Saver 1 plastic without a penny sleeve. Very Clear, in my opinion which is near worthless.
