Two brand new and sealed greeting cards (the large ones).  Two laminated trading cards (the small ones).  I bought all of them many years ago because I was a big fan.  One of the greeting cards features the man characters from RG Veda and Man of Many Faces, while the other features the main characters of CLAMP School Detectives.  I don't know for sure, but I suspect they may have been furoku back when CLAMP was drawing their first few series.
