Set of 4 Stackable Plastic Kitchen Storage Shelves (Foldable, White). Constructed from food-grade Polypropylene (PP) plastic, produced via a single-piece injection molding process. Single-unit dimensions (folded state): Length 32 cm, Width 20 cm, Height 3 cm; when unfolded, the height is approximately 12 cm (length and width remain unchanged). Non-expandable but stackable—each tier features interlocking protrusions (snap-locks) at its four corners. Manufacturing process: Plastic granule drying, injection molding (heating and injecting into the mold), pressure holding and cooling, demolding, and edge trimming. The foldable design is facilitated by a hinged structure. Suitable for organizing snacks, seasoning packets, and small bowls on countertops or inside cabinets.
