Portable Stainless Steel Thermal Lunch Box – Stack, Seal & Go

Meet your perfect meal-prep companion. This 3/4 Tier Insulated Lunch Box combines vacuum-insulated technology with a stackable, leakproof design so your food stays at the right temperature from home to wherever the day takes you — office, campus, camping, or outdoor dining.

Made in Mainland China.

Key Features

Double-Layer Vacuum Insulation: The outer jar slows temperature change, keeping soups, rice, noodles, stews, and pasta warm (or cold) for hours. For best results, preheat or pre-cool the jar with water before filling.
Stackable Tier Design: Choose between 3-tier or 4-tier removable containers to neatly separate your main meal, sides, sauces, fruit, and snacks — all in one compact jar.
304 Stainless Steel Construction: Food-grade 304 stainless steel inner jar and stackable containers paired with durable PP lids and handle parts — safe, sturdy, and built for daily use.
Leakproof Carrying Structure: Silicone sealing rings and a secure closure help prevent spills during transport. The top strap handle makes lifting and carrying effortless.
Wide Mouth for Easy Filling & Cleaning: The wide opening simplifies filling, serving, and rinsing. The polished inner surface wipes clean with minimal effort.
Two Capacity Options: Available in 2,000ml and 2,900ml sizes to suit individual meals or larger portions.
Eco-Friendly: Reusable and free from high-concern chemicals — a greener alternative to single-use containers.
