The invention relates to a front-open wafer box which mainly comprises a box body and a door body. A plurality of slots are arranged in the box body to accommodate a plurality of wafers, and an opening is formed at a side surface of the box body so as to input and output the plurality of wafers; and the door body is provided with an external surface and an internal surface, and has the function of protecting the plurality of wafers inside the box body by combining the internal surface with the opening of the box body. The front-open wafer box is characterized in that the door body is providedwith a sunken area integrally on the internal surface in order to divide the internal surface into two convex platforms; a limiting piece module is formed on each of the two convex platforms; each limiting piece module comprises a base; a plurality of grooves which are arranged at intervals are arranged on the base and are contacted with the plurality of wafers via the plurality of grooves.
