I use if for brochures, etc. but not prints I sell (which are generally
matte anyway).  With the acid test pen the interior paper does seem to test
as buffered.  That is the conspicuous difference between the Epson Premium
RC papers that are said to be archival and most of the other RC types of
papers, which are generally felt to be quite non-archival.  However, with no
statements from the seller about being acid free, that interior paper could
still have too much residual lignin in it.  So, the acid test pen is no
guarantee that the paper will last a long time.

Personally, my guess is that that paper is good enough for all uses except
sales that are explicitly said to be archival and acid free.  I suspect the
paper is good for most uses, and way better than the acidic papers that the
manufacturers admit are only good for 30 years.
