A clear plastic eraser shaving collector containing debris attached to a rainbow-gradient desk mat on a white table.

A realistic 3D product rendering and multi-view industrial design sheet of an innovative school stationery item: "Shitabiki (Japanese desk mat) with an integrated large-capacity eraser shaving collector." [Overall Design & Structure] The item consists of a colored, semi-transparent plastic desk mat and a large, horizontal, clear translucent plastic collector case attached directly to its very top edge. [CRITICAL STRUCTURE - Attachment Mechanism] - The desk mat does NOT continue underneath the case. - The collector case features a custom snap-fit joint (tabs and grooves, NO magnets) on its lower-front side that directly clicks ("snaps") onto the top edge of the desk mat. - Detachment: To remove the case, it must be slid horizontally away from the user (forward/backward slide, NOT lifting upwards) to disengage the snap-fit lock, allowing the user to detach the case and empty it into a trash can. [Eraser Dust Collection Mechanism] The case runs almost the full width of the desk mat to maximize volume. Eraser shavings can be swept directly upwards along the surface of the desk mat and straight into the wide opening of the case without needing to pick them up by hand. [Sliding Lid Structure] - The lid is NOT top-opening. - A horizontal sliding lid is built directly onto the FRONT surface (facing the user) of the case, sitting on a precise track. - CRITICAL: The lid slides fully from the absolute left edge to the right edge, exposing the entire length of the opening when fully Voir plus
