"e-mook" is something of a complicated brand name/portmanteau. "Mook" is a term used for Japanese publications that are somewhere between a magazine and a book. An "e-mook" is then publishers Takarajimasha's term for a mook enhanced with a bonus item, like a t-shirt or towel. Bandai has teamed up with designer-made t-shirts boutique Beams for a line of Digimon Adventure Tri inspired fashion, and a special eMook will be introducing the offering.
