Yeah, I know this is a long time ago. But I used to use it and it was pretty good. Their RC graded paper was better than many.
I used their graded black and white fiber exhibition papers back in the '70s when I was a kid. I remember that it was made in Japan, and I strongly believe that it was made by Oriental. When I got out of the Navy in 1981, I couldn't find it anymore, and I tried out some of the Oriental Seagull paper that some of my photo buddies were raving about, and I could not find any differencences between the Seagull and Unicolor papers WRT image quality and paper surfaces. And it was real cheap at that time
. I also tried the graded Oriental RC papers from that time and I felt that they were better than everybody else's RC papers.
