DC,, I don't know for sure,, but archival means it will last a long time ,, or that it is of quality for fine art,, India ink is I think as good as it gets,,, I have used repidograph pens, that have ink for architectural drawing,,but those pens I think are about 20 bucks,, my dictionary says" (of a material such as paper) of suitable quality to be used in archives. the illustrations are printed with archival inks that will last about 70 years. )" so if the ink is in fact archival,, it should work ,, I think it would last longer on wood with a finish on it,,
