large school pencil box is a large-capacity metal stationery box focusing on ample storage space and full-range use safety. Equipped with an ergonomic anti-pinch opening angle, it is specially designed for primary and secondary school students for classroom study, exam use, schoolbag storage and desktop stationery arrangement. It solves common safety hazards of large pencil boxes, including finger pinching caused by lid rebound, sharp edge scratching, hand injury from exposed hinges and box tipping due to unbalanced opening center of gravity. Combining large-capacity practicality and all-day use safety for children, it is perfectly suitable for school unified stationery procurement, supermarket stationery wholesale and cross-border bulk campus stationery orders. Most ordinary large school metal pencil boxes only expand internal capacity without complete safety protection design. Matched with unoptimized universal opening angles, they have heavier lids and stronger rebound force, bringing higher safety risks than small pencil boxes. Common defects include sharp burrs, fierce lid rebound causing finger pinching, easy tipping due to unbalanced opening angle, loud closing collision noise and hand scratching from exposed hinges. Such products fail to meet strict safety access standards for campus stationery despite large storage capacity.

　　This large school pencil box upgrades the full safety protection system from three aspects: edge appearance, internal structure and hardware accessories. Firstly, full-round arc edge polishing: all box edges, corners and opening cuts are processed with three-times fine polishing, removing all sharp metal burrs and incisions completely to avoid hand and finger scratches during holding, cleaning and storage, suitable for students of all ages. Secondly, hidden built-in hinge structure: different from exposed hinges of ordinary large pencil boxes, the hinges are embedded inside the box gap to prevent hand and book scratching, as well as finger pinching in hinge gaps. Thirdly, eco-friendly harmless material: it adopts food-grade safe tinplate and non-toxic matte coating, free of formaldehyde, heavy metals and pungent chemical odor, complying with European and American children stationery safety standards, bringing no health risks even if stored closely in schoolbags for a long time. Fourthly, reinforced durable hardware: hinges are welded firmly with full welding spots to prevent accessory falling off and fragment scratching after long-term repeated opening and closing, avoiding both physical injury and hidden health risks.

　　Considering the heavier lid weight and stronger rebound impact of large pencil boxes, we customize an exclusive 106° anti-pinch safe opening angle to improve dynamic use safety and fix the biggest safety defect of large stationery boxes. The universal 90° opening has short stroke and fast fierce rebound; the heavy lid will cause severe finger bruise and pinching injury. While opening angles over 110° will lead to severe center-of-gravity deviation, making the heavy large pencil box tip over easily and hurt users’ hands on the desktop.

　　The 106° golden safe opening angle perfectly matches the weight and opening stress of large pencil boxes. The lid can hover stably after opening without automatic rebound or sudden falling back, eliminating finger-pinching risks fundamentally. The gentle opening stroke and soft damping force require no extra strength to open the box, fitting students’ daily gentle operation habits. It provides complete unobstructed viewing vision for easy access to full sets of stationery without head collision. Besides, the lid closes slowly and evenly without harsh metal collision noise, avoiding disturbing classroom order and structural damage caused by strong closing impact. With large capacity to hold pens, rulers, erasers and correction tapes, as well as full safety design and humanized safe opening angle, this large school pencil box is a fully compliant and top-quality large metal pencil box for campus scenarios.
