The 79x67x21mm airtight child-proof lock tin box packaging is derived from the GEN1 child-proof lock tin can. Its structure consists of three parts: an outer hinged tin box, an inner tin body, and a foam gasket inside the lid. Its internal space boasts the highest level of sealing on the market, achieving heat insulation, 100% preservation of product flavor, and a stable child proof lock. Made from universal tinplate materials and produced using automated processes, it is a classic child-proof lock tin boxes that is both affordable and aesthetically pleasing, with a smooth-operating child proof lock.

This airtight tin box was completed in 2023, designed based on the product's dimensions. Its compact size was primarily to avoid the need for an inner tray, thus reducing the overall cost of the packaging. During production, an issue arose with oil burning at the rounded corners; however, this was completely resolved through modifications to the child proof lock mold and the selection of superior printing inks. This tin box can be considered an option in the high-end child proof lock tin box market.

Due to its height, the rounded corners are prone to showing white areas. The design primarily uses a single color scheme to mitigate this. This tin box requires gold foil printing, so the printing method uses white foam with gloss varnish for the gold parts and matte varnish for the background. However, the transparent metal metallic makes the entire cream background appear dull, which can only be mitigated by adding more white to the base color.

Its internal dimensions are 72x52mm, and it was originally designed to hold 14 pre-rolls. However, due to its versatile space and perfect seal, this tin box can be packaged in a non-stick gummy way by adding a butter paper insert.
