Multi-Layer Stainless Steel Insulated Lunch Box

This is a large-capacity, multi-layer insulated lunch box available in 1–4 stackable layers. Each layer can be used independently with its own sealed lid, ensuring no cross-flavor contamination. The 304 stainless steel interior uses a microwave copper-plating process, and the space between the inner stainless steel wall and the PP outer shell forms a double-insulated structure that keeps food warm for up to two hours. Its biggest advantage is that it can be used in a microwave oven (with the vent opened), making it ideal for outdoor camping or daily meal carrying.
