❤️Dining on the move has never been more enjoyable and simple as with this tiered lunch box.


🚗Are you gearing up for a trip? Do you prefer bringing your meals to work? Keep them in a secure environment and eliminate concerns about germs. Bringing your own food guarantees that you and your surroundings remain uncontaminated.


🍚Would you like your meals to remain hot and fresh, even hours after they've been prepared? Then this thermal lunch box is a must-have for you. It can be tough resisting unhealthy snacks, but having nutritious meals ready is the best way to stay on track! Especially with its attractive design, which is ideal for starting conversations at lunchtime!

FEATURES

  • Superior insulation – With the vacuum insulation and insulated bag, your meals stay warm for 3-4 hours; nearly double the duration of other options. Say goodbye to cold lunches. Microwaves are no longer necessary! The vacuum insulation keeps your food warm and wholesome, allowing you to relish a delicious homemade meal at school or the office.

  • Premium materials – Both the inner and outer materials are crafted from high-quality, food-safe stainless steel SS304 which is rust-resistant and naturally free of BPA. It won’t alter flavors or scents, enabling the box to be reused many times. The handle and divider are created from food-grade plastic.

  • Leak-proof & drip-resistant – Durable silicone seals are positioned between each insulated section to maintain freshness, prevent spills, and eliminate odors. Ensure the connections between layers are secure to avoid leaks. Don’t forget the silicone valve at the bottom of each layer, which keeps it leak-proof.

  • Convenient lunch bag – Crafted from high-quality Oxford fabric, it not only enhances insulation but also simplifies transportation.

  • Ideal for portion control – Pack it with rubber bands and gift it to someone special so they can savor homemade delights for a healthier lifestyle!

USAGE AND CARE GUIDELINES

  • After each use, wash all components with a mild, diluted cleaning solution, a soft cloth, and warm water. Dry them with a soft sponge, cloth, or brush. Keep in a cool, dry space.

  • The stainless steel layers cannot be used in the microwave. However, the non-metal layers can be safely microwaved. To avoid damage, do not utilize bleach, chlorine, or steel wool for cleaning. Allow the lid to remain open for 30 seconds after filling with hot liquids.
