2-Tier Stainless Steel Thermal Lunch Bowl
Hot Meals, No Microwave Needed
Forget about cold sandwiches or radiation from the office microwave. This thermal lunch bowl uses double-wall insulation technology (a layer of air between the stainless steel and outer plastic) to minimize heat loss. It keeps hot food warm and cold food chilled for hours, giving you the freedom to eat anywhere.
Premium Materials for Healthy Eating
Your health comes first. The inner bowls are forged from high-quality food-grade 304 stainless steel. Unlike plastic, this material is non-porous, meaning it won’t stain, retain curry smells, or leach chemicals into your hot food. It is durable, corrosion-resistant, and effortless to wipe clean.
Smart 2-Layer Separation
Don’t let your curry turn your rice into mush. The 2-tier vertical design lets you separate wet and dry ingredients.
Top Tier: Perfect for soups, stews, or wet curries (usually features the strongest seal).
Bottom Tier: Ideal for rice, noodles, or dry sides.
User-Friendly Design
Pressure Release Valve: Hot food creates suction. The built-in air vent lets you release steam so you can open the lid easily.
Cool-Touch Exterior: Even if the food inside is piping hot, the outer plastic shell remains cool to the touch, preventing burns.
Secure Locking: Heavy-duty snap-on clamps hold the tiers together firmly.
