Bentgo MicroSteel Stainless Steel Leak-Proof Bento Lunch Box, 5-Cup with Removable Divider & Vent

Bentgo MicroSteel is a 5-cup, leak-proof stainless steel bento that safely reheats in the microwave using MicroSteel technology—no plate or transfer required.

This lunch box combines stainless-steel durability with an airtight lid and a user-friendly vent so you can store, transport, and reheat meals in one container. Designed for everyday meal prep, leftovers, and on-the-go lunches, the removable divider and secure silicone seal make portioning and spill prevention simple. Built from food-grade, BPA- and PFAS-free materials, it’s dishwasher-safe on the top rack and intended for ages 13 and up.

How does MicroSteel let me reheat food in the microwave?

MicroSteel technology is engineered to make stainless steel safe for short microwave reheating by controlling how the container interacts with microwave energy. You still use the silicone vent to release pressure before opening, and the design avoids the need to transfer food to another dish.

• Reheat directly in the lunch box for quick meals.
• Use the venting valve to safely release steam before removing the lid.
• Suitable for short reheating cycles—follow recommended time and power settings.

Is the Bentgo MicroSteel really leak-proof for travel and backpacks?

The lid features a snug silicone seal that forms an airtight barrier to help prevent leaks during transport. A sturdy snap closure keeps the lid secured, reducing spills from bumps or tilts when commuting or packing in a bag.

• Silicone gasket creates an airtight, spill-resistant seal.
• Snap-lock lid designed to stay closed under normal travel conditions.
• Ideal for salads, grain bowls, soups (when upright), and layered meals.

How do I clean and maintain the lunch box to keep it lasting?

The bowl and stainless-steel interior are top-rack dishwasher-safe for easy cleanup, while hand washing the lid is recommended to preserve the silicone seal and vent longevity. Routine cleaning of the valve and gasket prevents odors and keeps the airtight performance strong.

• Top-rack dishwasher safe for the steel body.
• Hand wash the lid and silicone parts to prolong seal life.
• Disassemble divider and gasket for thorough rinsing and drying.

What can fit inside and how flexible are the compartments?

The removable divider lets you split the 5-cup capacity into two custom portions for balanced meals, snacks, or sides. Use it full-size for a single meal or add the divider for two items without mixing flavors or textures.

• 5-cup capacity holds a main dish plus side or two medium portions.
• Removable divider for portion control and separation of wet and dry foods.
• Compact footprint fits most lunch bags and standard refrigerators.

Who is this for? The Bentgo MicroSteel lunch box suits busy professionals, students aged 13 and older, and anyone who prefers prepping meals at home but wants the convenience of reheating without dish transfers. It’s a practical pick for commuters, office workers, and meal-preppers who value durable materials, leak resistance, and easy cleanup in one compact container.
