User @GrPpUi84aS95409 on Twitter has posted photos of pages of ECole Office Supply Catalog. Most of these pages are concerning Pentel, but there are other brands scattered in there as well.
I have taken these pictures and put them together as PDFs and put them in my Pentel Catalog directory ( Dropbox ).
There are 24 catalogs (years missing - 1996, 1998, 2004 & 2006), but I suspect that 1996 may have been merged in with 1995. These have the cover of the catalog and 1 to 3 additional pages of listings.
This has given me a BUNCH of additional information for Pentel pencils, and hopefully it will help out other users.
