Bentoheaven Bento Box Adult Stackable Lunch Box 40 oz — Two-Tier, Leak-Resistant with Removable Divider

The Bentoheaven Bento Box Adult is a two-tier, 40 oz stackable lunch box designed to carry a full adult meal with separate compartments and a silicone-sealed lid for leak-resistant storage when properly closed.

This compact, Japanese-inspired bento combines two 20 oz containers with a removable divider and a dip cup so mains, sides and sauces stay apart. Finished with a wood-grain style lid and a secure strap, the design fits typical workplace refrigerators and lunch bags while keeping portions controlled. Materials are lab-tested BPA-free, the containers are microwave- and dishwasher-safe (lid off or top-rack), and each set includes reusable utensils plus a 30-recipe e-book.

How does the two-tier layout make meal prep easier?

The Bentoheaven two-tier layout separates foods so flavors and textures don’t mix during transport. The removable divider and included dip cup let you portion proteins, grains and sauces separately, simplifying meal assembly for balanced lunches.

• Two stackable 20 oz containers giving a 40 oz total capacity
• Removable divider to create two compartments in one tier
• Small dip cup included for dressings, dips or condiments
• Wood-grain lid for a stylish, desk-friendly appearance

Is the Bentoheaven box safe for hot or saucy foods?

The box is built for saucy preparations when sealed correctly: a silicone gasket in the lid and an air-vent plug help secure liquids. For best results, press the plug fully into place to lock the seal and keep very liquid items upright while transporting.

• Silicone-sealed lid with a built-in air-vent plug for easier opening
• Leak-resistant when the plug and lid are properly seated
• Keep containers upright for thin soups or very runny dressings
• Lid removal recommended before microwaving contents

What care instructions should I follow to keep it long-lasting?

Materials are lab-tested and BPA-free; handle the lid and silicone parts with care to preserve the seal. The bowls are microwave-safe (use without lid) and dishwasher-safe on the top rack, while frequent high-heat cycles may gradually wear silicone components.

• Microwave-safe with lid removed to vent steam
• Dishwasher-safe on the top rack to avoid excessive heat stress
• Inspect and reseat the silicone plug regularly for reliable sealing
• Hand-wash the lid and silicone parts if you want to extend gasket life

What extras come with the Bentoheaven set?

Each purchase includes a complete reusable utensil kit—fork, spoon, knife and chopsticks—plus a sealing strap that holds the tiers together and a downloadable 30-recipe e-book for lunch inspiration. The brand also supports Feeding America with purchases.

• Reusable fork, spoon, knife and chopsticks in the utensil set
• Sealing strap to hold stacked tiers securely during transport
• 30-recipe e-book to help plan balanced lunches
• Portion-controlled 7.3 × 3.9 × 4.1 in sizing for adult meals

Who is this for: The Bentoheaven Bento Box Adult suits office workers, commuters and anyone seeking a compact, portion-focused lunch system that keeps components separate. It is ideal for people who pack homemade meals with sauces or dressings, prefer reusable utensil sets, and want dishwasher- and microwave-friendly containers that fit standard lunch space constraints. Check the 7.3 × 3.9 × 4.1 in dimensions and 40 oz capacity to confirm it meets your portion and bag size needs.
