A 4-Grid 304 Stainless Steel Bento Lunch Box — Thermal Insulation Base, 300ml Soup Bowl, Silicone Seal, 4-Side Lock, 1500ml Total Capacity

Key Features

• 4-grid divided interior — the stainless steel tray is divided into four sections: one large compartment for a staple such as rice or noodles, two smaller compartments for sides and vegetables, and one circular recess that seats the included 300ml soup bowl; the four-grid layout keeps food separated and prevents flavour transfer between dishes during transport
• 304 stainless steel food-contact surfaces — the inner tray and soup bowl are 304 stainless steel; food-grade, non-toxic, with rounded internal edges and no burrs; easy to clean and resistant to odour absorption compared to plastic alternatives
• Thermal insulation base — the base of the lunch box is filled with water before use; hot water in the base keeps the stainless steel tray warm from below, maintaining meal temperature during transport and without requiring electrical power; fill with hot water before travel, not during carrying to avoid burns
• 300ml stainless steel soup bowl — a separate 300ml soup bowl is included and seats securely in the circular recess of the inner tray; allows a soup, broth, or sauce to be carried alongside solid food without mixing into the main compartments
• Silicone sealing ring with 4-side locking clips — the lid is fitted with a silicone sealing ring and secured by four-side locking clips; provides a secure seal that prevents liquid from the soup bowl and main tray from leaking during transport; keep the box flat after filling with water in the insulation base to avoid spillage
• Three colours: Pink, Green, Blue — the outer shell and locking clips are available in three colours; select one colour per order; the stainless steel interior is the same across all colour options
• Includes spoon and chopsticks — a spoon and a pair of chopsticks are stored in the lid; the set is self-contained for office, school, and travel use without requiring additional utensils

Designed For

• Office workers and students who carry home-cooked meals and want to keep rice, sides, vegetables, and soup separated and warm until lunchtime; the four-grid layout and thermal insulation base directly support a full balanced meal in one container
• Anyone who wants to bring a soup or broth alongside a solid meal; the dedicated 300ml soup bowl with its recessed seat in the tray makes this practical without the need for a separate container
• Meal prep routines where food is portioned and stored in advance; the four compartments allow a complete meal to be assembled and sealed the night before
• School canteen and classroom lunch use; the compact rectangular form, durable 304 stainless steel, and 4-side locking clips are well suited to a school bag environment where the box may be handled roughly or stored at an angle
• Home family meals where individual portions are plated and kept warm without using a microwave or hob for reheating

Why Choose This

The combination of a four-grid stainless steel tray, a dedicated soup bowl, and a thermal insulation base addresses the three most common practical shortcomings of standard lunch boxes: food mixing during transport, no way to carry a liquid dish alongside solid food, and food that arrives cold. The 304 stainless steel food-contact surfaces are durable, odour-resistant, and easy to clean. The 4-side locking clips and silicone seal provide a leak-resistant closure suited to daily commuting. The spoon and chopsticks stored in the lid complete the set without requiring additional accessories.

FAQ

Q: How does the thermal insulation work?
A: The base of the lunch box has a water chamber. Fill it with hot water before placing the inner tray, then close and lock the lid. The hot water in the base heats the stainless steel tray from below, keeping the food warm. Fill with hot water only before travel — do not fill during carrying to avoid burns. Keep the box flat after filling to prevent water movement.

Q: Is the soup bowl leak-proof during transport?
A: The soup bowl seats securely in the circular recess of the inner tray. The 4-side locking clips and silicone sealing ring on the lid provide a seal that significantly reduces leakage of liquids. For best results, avoid overfilling the soup bowl and keep the box flat during transport.

Q: Can the stainless steel inner tray and soup bowl go in the dishwasher?
A: Hand washing the stainless steel inner tray and soup bowl is recommended to preserve the finish and the silicone sealing ring. The outer PP shell should not be submerged in water.

Q: Is this suitable for hot food or reheating?
A: This lunch box uses a hot water thermal insulation base to keep food warm — it is not an electric heating appliance and cannot reheat food from cold. Pack food hot and the insulation base will maintain temperature during transport. Do not use in a microwave.

Q: Is the 304 stainless steel safe for acidic foods?
A: 304 stainless steel is a food-grade material suitable for most cooked foods including acidic dishes. It does not leach flavours or absorb odours, making it well suited to a variety of meal types including those with sauces and dressings.
