Assorted Precision Metal Shims/Spacers

The image displays a collection of what appear to be custom-cut metal shims or spacers, contained within a simple cardboard box. Each piece is generally rectangular or square, though many exhibit precise cut-outs, notches, and internal slots, suggesting they are designed for a specific interlocking or spacing function within an assembly. The material appears to be a light-colored metal, most likely aluminum or a similar alloy, given its matte, silvery-gray finish and the absence of rust or significant oxidation. The individual pieces vary in size and cut-out patterns, indicating either a mixed set of components for different applications or components that interlock to form a larger structure. The edges appear to be precisely machined or stamped, showing clean lines and sharp corners, which speaks to a good level of craftsmanship and manufacturing quality. There are no obvious signs of wear, heavy damage, or extensive patination, suggesting these are either new components or have seen very little use. Some pieces show minor surface scratches, likely from handling and being stored together in the box. No discernible maker's marks, signatures, or stamps are visible on any of the pieces. Based on their appearance and uniformity in material and finish, these items likely originate from a modern industrial manufacturing process, possibly within the last few decades, as they do not show characteristics of older, hand-forged or less precise fabrication methods. Their purpose seems to be functional rather than decorative, designed for precision fitting or spacing within mechanical or structural applications. The cardboard box itself is a standard shipping or storage box, showing some minor wear and tear consistent with industrial packaging.
