Collect with Peace of Mind, Safety as the Core — collectible tin boxes, with "comprehensive safety protection and high-standard quality control" as the core, breaks the limitation of ordinary collectible boxes that "substandard materials, potential process hazards and no safety guarantee". Deeply focusing on the safety needs of collection scenarios, it builds a comprehensive safety system from material selection, process polishing, safety testing to detail design, balancing collection value, ornamental value and safety value. It is suitable for storing various precious collections such as antiques, stamps, badges, jewelry and commemorative coins, allowing every collection to be properly preserved in a safe environment. With strict safety standards, it guards every collection intention, becoming a reassuring choice for collectors and highlighting the style and peace of mind of collection.

　　Strict material safety, eliminating hidden dangers from the source. Adhering to the principle of "safety first", collectible tin boxes are made of food-grade high-purity tin alloy and thickened tinplate, rejecting inferior metals and harmful additives. The material purity is ≥99.9%, which has passed strict material screening and purification treatment, with no heavy metal residues such as lead, mercury and cadmium. The heavy metal content is ≤0.001mg/kg, complying with the national food safety standard GB 4806.9-2016 and the dual international certifications of FDA and CE. It has no peculiar smell and no harmful gas emission, and can directly contact various precious collections without causing corrosion, oxidation or pollution to the collections, eliminating material safety hazards from the source. Compared with ordinary tin boxes, collectible tin boxes have purer materials and finer textures, which not only have good moisture-proof and anti-oxidation performance, but also can avoid damage to collections caused by the materials themselves, providing comprehensive material safety protection for easily damaged collections such as antiques and stamps.

　　Exquisite process safety, all-round protection without dead ends. Relying on refined production technology, each collectible tin box undergoes multiple safety polishing and testing processes to completely eliminate process hazards. The box body adopts a seamless welding process, with flat and smooth welds, no missing welding, false welding, burrs and other problems, avoiding sharp edges and corners scratching collections or collectors; the edges go through 12 fine polishing processes, round and smooth, with a delicate touch, without any sharp edges and corners, which not only protects the collections from wear, but also ensures the safety of collectors when taking them. The surface adopts environmentally friendly electrostatic spraying and high-temperature curing technology, using odorless and non-volatile environmentally friendly ink. The coating adhesion reaches grade 4B, which is not easy to fall off or scratch, and has no harmful volatiles. It will not cause pollution when in long-term contact with collections. At the same time, it has good scratch-proof and rust-proof performance, avoiding the box body rusting and polluting collections, and the details show the rigor of process safety.

　　Comprehensive safety testing, compliant and reassuring. Each batch of collectible tin boxes undergoes full-process safety testing, building a three-level testing system of "material testing - process testing - finished product testing", with a qualification rate of 99.9%, ensuring that each product meets safety standards. In the material testing link, it focuses on testing heavy metal content, material purity and harmful substance emission, eliminating unqualified materials from entering production; in the process testing link, it checks process details such as welds, edges and coatings to ensure no safety hazards; in the finished product testing link, it conducts multiple tests such as moisture-proof, anti-oxidation, sealing and load-bearing to ensure that the tin box can stably guard the collections for a long time. At the same time, the product can provide a complete test report, which is compliant and up to standard, adapting to various scenarios such as home collection, museum display and gift collection, allowing collectors to collect and store with peace of mind without worrying about safety issues.

　　Upgraded protection safety, all-round protection of collections. Aiming at the storage needs of various collections, the collectible tin box creates an exclusive safety protection system, balancing collection safety and storage convenience. It is equipped with a food-grade flocked inner lining, which is soft and delicate, effectively buffering collisions, shock absorption and scratch prevention, avoiding the collections from being worn and collided during storage or carrying, especially suitable for easily damaged collections such as stamps, badges and jewelry; it is equipped with a double sealing design, the can mouth is equipped with a food-grade silicone sealing ring and a metal buckle lock, with excellent sealing performance and an air leakage rate of ≤0.003%, which can effectively block air, moisture, dust and harmful gases, prevent the collections from being damp, oxidized and faded, and extend the collection preservation period. In addition, the box body adopts anti-corrosion and anti-aging design, with a temperature resistance range of -25℃ to 130℃, which can be adapted to storage in different environments, avoiding damage to collections caused by environmental changes, comprehensively protecting the safety of collections, and allowing every precious collection to be preserved for a long time.
