Looking for Thick Mylar/Arhival Sleeves

[alphaNumis]

Hi, I am looking for thick Myalr type sleeves, with a top opening to keep my banknotes. Specifically, I am looking for archival quality (acid free) types and the thickness has to be equivalent to those used by PMG or other grading companies.

 

Anyone here know where I can get them?

 

I've tried SAFE, 20 mil sleeves but they are too soft.

 

Thanks.

Thanks for the tip but I can't seem to find any think Mylar holders. I only see acrylic type with screws.

 

I am looking for the paper money holder used by PMG.
