Combination Lock Tin Box | Custom Metal Lock Box for Secure Storage & Promotion
A combination lock tin box is a metal storage container fitted with a code lock, designed for keeping small personal items such as coins, cards, jewelry, keys and USB drives organized and out of casual reach. It is not a professional safe — its value lies in portable organization plus a psychological deterrent, making it ideal for desktop storage, home use and promotional giveaways. As a tin box manufacturer, we support full customization from mold selection to surface printing, with adjustable sizes and artwork.
Common Sizes and Materials
Combination lock tin boxes are available in multiple size tiers to match different storage needs. Mini models around 125×95×55mm suit coins and keys; small models around 150×120×80mm fit a phone or bankbook; medium models around 200×160×90mm accommodate banknotes and documents; large models around 250×180×90mm hold certificates or an A5 notebook. Most products use tinplate or cold-rolled steel, with thickness from 0.23mm standard tinplate up to 1.0mm reinforced plate. Note that 0.2–0.3mm tinplate offers limited pry resistance — the lid flexes under hand pressure — so it is better suited to deterring casual snooping than withstanding forced entry.
Lock Types and Pry Resistance
Locks fall into two main categories: mechanical combination wheels and key locks. Mechanical wheels are commonly 3-digit or 4-digit; a 4-digit code offers 10,000 combinations and takes far longer to brute-force. When judging pry resistance, check the latch structure: a hidden latch embedded inside the body, with no external stress point, resists prying better than an exposed shackle, and dual latches locking simultaneously are harder to open than a single-point lock. A simple twist test helps during procurement: grip both ends and twist gently — a quality box stays rigid, while a poor one distorts and shows gaps at the latch. For low-to-medium security needs such as private savings or jewelry, a tinplate box with a 3-digit combination is sufficient.
Customization and Surface Finishes
As a source factory, we offer full customization of combination lock tin boxes. Surface printing supports CMYK four-color offset printing for clear brand patterns and text on lid and body. Finishes include glossy, matte and embossed relief to add tactile and visual depth. Lock configuration can be chosen to budget, from basic mechanical wheels to upgraded latch structures. EVA foam or flocked inserts can be added to secure jewelry and small electronics. MOQ and tooling costs depend on size and lock solution; existing stock molds are free to use, reducing setup costs.
FAQ
Q: Can a combination lock tin box stop a thief?A: No. It is portable storage with a psychological deterrent, not a professional anti-theft container. Budget models can typically be pried open with an ordinary flathead screwdriver in a short time. For real anti-theft protection, choose a small safe with an electronic code and alarm.
Q: What if I forget the code?A: Mechanical wheel boxes usually have no emergency unlock. Record the code in a safe place after setting it. Some resettable models have a reset lever on the bottom or inside; confirm with the supplier whether a specific model supports resetting.
Q: Will the tin box rust?A: Tinplate has a tin coating for rust protection, but cut edges and prolonged damp conditions may still oxidize. Sprayed or film-laminated surfaces resist rust better. A dry storage environment is enough for everyday use.
Q: Can size and printing be customized?A: Yes. We adjust length, width and height to your requirements; artwork files are provided by the customer, and mass production begins after sample confirmation. Stock mold sizes are free to use; special sizes require confirmation of tooling cost and lead time.
Q: Is it suitable as a promotional giveaway?A: Yes. It combines practicality with an unboxing ritual and is widely used for bank customer rewards, corporate gifts and branded merchandise. The tin box is reusable and recyclable, supporting sustainability goals. A basic tinplate model with single-color printing controls cost while keeping customization space.
