The invention and additional space for receiving a predetermined amount of moss as relates to environmentally friendly moss block using a MOS (Moss, moss) for recording or sound insulation, such as for aesthetic decoration or the like wall, a top-open cube-like form, the lower at predetermined intervals on the upper surface with a plurality of barrier ribs it is formed to a predetermined height, frame with a plurality of slits formed at intervals on both side faces which faces the upper edge; At least one separating member provided so as to partition the space of the mold parts in a direction perpendicular to the partition wall, and the space portion comprises a string that is parallel to a fixed over a plurality of the slit and the slit formed in the both side edges, and the partition wall and the separating member is formed to secure the moss by the characters contained in addition to that also Moss not evenly distribute the tipping frame so that one side is a moss is not separated from the frame. The invention any artificial material by the rich volume and soft texture of providing a sensory interior and analog sensitivity plus the sensitivity of vivid nature depending on the arrangement or array of the MOS block Scandinavian moss is fixed to produce a variety of colors to the mineral conservation in addition to providing an inexpressible beauty to combine the moisture retention and sound absorption and fire resistance of the space.
