This 2-piece set of kitchen countertop organizers is constructed from a blend of metal and engineered wood, featuring a color scheme of deep black and natural beige. The metal support frames are formed using continuous stamping and spot-welding techniques, finished with a matte surface coating; the engineered wood shelves are cut, edge-banded, and pre-drilled before being assembled to the metal components using screws. The entire unit is both stackable and expandable, with the expansion mechanism facilitated by smooth-gliding metal rails that allow the rack to extend up to approximately 52 cm in length. When used independently, each rack serves as a convenient organizer for spices or tableware; when stacked, they significantly increase vertical storage space. The manufacturing process prioritizes smooth, rounded edges to prevent scratches and ensure user safety.
