1. A tissue product with at least four plies made of tissue paper base sheet or nonwoven, comprising:
a first outer ply and a second outer ply and at least two inner plies between the first outer ply and the second outer ply,
wherein
only one of the inner plies is un-embossed;
at least one of the outer plies comprises a décor embossing pattern;
at least two adjacent inner plies comprise the un-embossed inner ply and one micro-embossed inner ply; and
the outer plies comprise a micro-embossing pattern, wherein either the density of the micro-embossed protrusions of the micro-embossed inner ply is different to the density of embossed protrusions of the micro-embossing pattern of the outer ply which is adjacent to the micro-embossed inner ply or the micro-embossed protrusions of the micro-embossed inner ply and the embossed protrusions of the adjacent outer ply are not in register with one another.
