Key Selling Points

🌟 High-Quality Material, Safe and Reliable Dining

The inner liner and food container are made of food-grade 316L stainless steel. Compared to ordinary 304 stainless steel, it has stronger corrosion resistance and wear resistance. It is less prone to rusting and leaching of harmful substances even after long-term contact with acidic or alkaline foods, meeting daily food safety standards. Double-layer heat insulation and anti-scalding design insulates against the high temperature of the inner liner, preventing burns when handling, balancing practicality and safety.

⏰ Long-Lasting Insulation and Freshness Preservation, Maintaining the Temperature of Meals

Equipped with high-temperature vacuum insulation technology and a multi-layer insulation structure, it achieves 12-hour long-lasting insulation (above 60℃) and 24-hour continuous temperature retention. The four-layer independent inner bowl design allows for separate storage of rice, soup, porridge, and fruit, effectively preventing flavor mixing. Hot dishes, soups, and cold foods can all be precisely temperature-controlled, ensuring that whether you bring a hot breakfast to the afternoon or refrigerate leftovers overnight, the original taste and flavor of the ingredients are preserved.

🧳 Portable and thoughtful design, stress-free travel

The one-button press-to-open design allows for easy one-handed operation, perfect for busy commuters and students. The food container features an independent handle for effortless layering and easy access to the inner bowls. The foldable, flexible handle saves storage space and is compact for easy carrying. Multiple anti-overflow sealing structures, combined with a sealing lid and sealing ring for double protection, prevent leakage even when inverted or shaken, making it safe to carry during commutes, work, and outdoor excursions.

📦 Large Capacity, Layered Fit to Meet Diverse Dietary Needs

Offering two sizes: a 2.7L four-layer version (suitable for men and those with larger appetites) and a 2.2L three-layer version (suitable for women and students), precisely matching different food intake needs. The four-layer inner bowls have capacities of 340mL, 340mL, 500mL, and 500mL respectively, while the three-layer inner bowls have capacities of 340mL, 500mL, and 500mL. This allows for flexible mixing of staple foods, meat dishes, vegetables, soups, and porridges, satisfying all types of dietary needs for a full meal without the need for additional portioning.

🔋 Versatile and Versatile for Multiple Scenarios

The food container is microwave-safe (it can be placed directly in the microwave after removing the lid for more even heating). The 316L inner pot can be used for steaming egg custard and heating other foods, making it ideal for home heating. It can also be refrigerated to keep food fresh and extend its shelf life, perfect for advance meal preparation. It comes with stainless steel cutlery (chopsticks and spoon) and a dedicated insulated bag for convenient storage. The insulated bag further enhances insulation, making this complete set a one-stop solution for dining out, bringing your own food, and delivering meals.

Usage Guide

✅ Correct Usage Steps

Before first use, wash the inner container, food container, and accessories with warm water to remove any remaining protective film. Let them air dry.

For heating, prepare the food and place it in the inner bowl. Remove the inner bowl lid and microwave (do not heat with the lid on to avoid expansion and damage).

For everyday lunches, place different ingredients in their individual inner bowls, tighten the sealing lids, assemble, and place in the main insulated container. Secure the buckles to carry.

For refrigerated use, simply place the food in the refrigerator's crisper drawer. No disassembly is required when taking out the food; simply carry it directly.

❌ Precautions

Do not dry-heat the inner liner. Do not place the main body of the insulated container directly into heating devices such as microwave ovens or ovens.

Avoid strong impacts or drops to prevent deformation of the inner liner, which may affect the insulation effect.

When cleaning, avoid using steel wool or hard-bristled brushes to prevent scratching the 316L stainless steel surface. It is recommended to clean with a soft cloth and warm water.

When not in use for extended periods, thoroughly dry the product and store it in a dry, well-ventilated place to prevent the growth of bacteria due to moisture.
