This is a highly creative 3-digit combination lock box, featuring a classic dial-lock design. By rotating the three numeric rings, users can set a personalized password; only the correct code will unlock the inner compartment, combining practical storage with playful fun. The main body is shaped like a cylindrical pen holder, making it ideal for storing small personal items such as paper clips, USB drives, loose change, and tiny jewelry—or it can double as a desk pen holder for organizing writing instruments, maximizing its utility. The three-color numeric-ring design makes password setting more intuitive, assembly is straightforward, and once printed, the pieces can be easily snapped together for immediate use, making this a practical yet entertaining little desktop accessory.
