The item you've specified is a popular type of Bento-style food container designed for healthy and separated meal packing.

Here is a breakdown of the key features and characteristics of a 304 Partition Stainless Steel Lunch Box - MultiColor:

Key Features

1. Material:

   • 304 Stainless Steel (Inner Tray): This is a high-quality, food-grade stainless steel known as "18/8" (18% Chromium, 8% Nickel). It is durable, rust-proof, stain-proof, and does not leach chemicals into food, making it a safe, eco-friendly choice.

   • Outer Body: The outer shell is often made of a durable, food-grade plastic (like PP). This outer shell is what provides the vibrant "MultiColor" options (e.g., pink, blue, green, white).

2. Partition/Compartment Design:

   • The core feature is the partitioned inner tray, which typically has 2, 3, or 4 distinct compartments.

   • This design keeps different food items (main course, side, snack, fruit) separate, preserving their original taste and making portion control easier.

   • Important Note: While the main lid is usually leak-proof, the internal partitions generally separate dry food but do not create individual liquid-tight seals between the compartments.

3. Cordless and Heating Features (Varies by Model):

   • Standard Model: Many models are not microwave safe due to the stainless steel, so food must be eaten cold or heated externally.

   • Insulated/Thermal Model: Some feature double-wall insulation or allow you to pour hot water into the plastic outer layer to keep the stainless steel tray warm for a short period.

   • Microwavable Model: Some advanced models are designed so that the stainless steel inner tray is removable, allowing the plastic outer container to be safely microwaved (you would heat the food in a separate dish and transfer it, or just use the plastic part).

4. Security and Portability:

   • Leak-Proof Seal: The main lid usually has a silicone sealing ring and is secured with lockable clips/latches on the sides to prevent spills when carrying.

   • Portability: They are compact, lightweight, and suitable for school, office, travel, or picnics.

5. Included Accessories:

   • Many of these lunch boxes come as a set, which may include:

     • Matching Spoon and Chopsticks

     • A small soup or sauce container

     • An Insulated Carry Bag (often a random coordinating color).
