Rare item. Manifold refers to a slightly harder nib for carbon paper. Because it can be written with strong pressure, it is highly popular both in the past and now. I tried it, and the ink does not come out. Since it is an old item, we decline those seeking a beautiful item. Returns are not accepted to prevent replacement.
