Hello,
I am looking for a matte paper that is 100% cotton, acid-free, lignin-free, and unbuffered, with no OBAs. The size I need is at least 25 inches x 20 inches. Are you able to recommend one because I have not been able to find one on your website that will meet all these needs. I am looking to print a high quality reproduction of an old map.

The only unbuffered paper we offer is Cosmos Blotting, but this is alpha-cellulose and not cotton.

Unfortunately, we do not offer an unbuffered cotton papers.
