The Asude Rectangle 4-Piece Airtight Container Set (often cataloged as the Oblong Set) is a versatile, high-quality storage solution designed to maximize space in your fridge and pantry. These rectangular containers are specifically favored for items like sliced deli meats, long vegetables, and shallow-stacking leftovers. Set Composition & Sizes This set typically follows the standard Asude graduated sizing, allowing the smaller units to nest inside the larger ones for compact storage when empty. 500 ml: Perfect for small snacks, berries, or dipping sauces. 900 ml: Ideal for side dishes, prepped salad greens, or a small block of cheese. 1500 ml (1.5L): Great for standard leftovers like pasta, stews, or pre-cut fruit. 2400 ml (2.4L): The largest in the set, designed for bulk meal prep, larger cuts of meat, or family-sized servings. Key Features Feature Details Airtight Seal Features a heavy-duty lid with a silicone gasket and a 4-way locking system to prevent leaks and keep food fresh. Material Made from durable, BPA-free transparent plastic that provides glass-like clarity with shatter-proof safety. Temp Safety Safe for use in the freezer and dishwasher (top rack recommended). Microwave Safe for reheating; however, always remove the lid before placing it in the microwave. Design The flat, rectangular (oblong) shape allows for stable stacking, making them more efficient for low-profile shelves. Why Choose the Rectangular (Oblong) Set? While square containers are great for deep cabinets, the rectangular shape of this set is often more practical for standard refrigerator shelves. Their elongated footprint allows you to push them to the back of the fridge while still seeing what's inside, and they are easier to fit into lunch bags for school or office workers.
