Zojirushi Mr. Bento Vacuum-Insulated Stainless Lunch Jar 41 oz Carbon Black - 4 Microwaveable Bowls

Designed for people who want to transport a complete, multi-course lunch without separate containers, the Zojirushi Mr. Bento combines a durable stainless outer shell with four stackable, microwave-safe inner bowls. The vacuum-insulated exterior helps maintain food temperature, while the removable bowls let you pack everything from soup to salad to dessert in one compact unit. Its carbon black finish looks sleek and the included forked spoon and carrying bag make it convenient for work, school, or travel.

How does the Mr. Bento keep different foods fresh and separate?

The jar uses four individual inner bowls that nest inside a vacuum-insulated stainless container, so each dish stays compartmentalized and flavors don’t mix. The bowls snap closed with clip-on lids, making it easy to carry multiple items without spills.

• Main bowl 15 oz for a hearty entrée.
• Large side bowl 10 oz for rice, pasta, or vegetables.
• Small side bowl 7 oz for snacks or sides.
• Soup bowl 9 oz designed to hold broths or stews.

Can I heat or cool food in these containers?

The outer stainless jar provides vacuum insulation to help preserve hot or cold temperatures during transit. The four inner bowls are made of microwave-safe plastic so you can remove a bowl and reheat its contents quickly when you’re ready to eat.

• Vacuum insulation reduces heat transfer for longer temperature retention.
• Microwaveable inner bowls for reheating individual portions (use bowl only, not outer container).
• Nonstick coated interior of the jar for easier cleaning.
• BPA-free materials throughout for safer food contact.

What accessories and build details come with the lunch jar?

The package includes a forked spoon with its own cover and a carry bag that fits the entire jar, so you have utensils and protection on the go. The outer container is stainless steel for durability, while the inner bowls are lightweight and stack neatly inside.

• Included forked spoon with protective cover for mess-free storage.
• Easy-to-carry insulated bag holds the jar and accessories.
• Durable stainless steel exterior resists dings and supports vacuum insulation.
• Clip-on lids ensure inner bowls stay sealed during transport.

How easy is it to clean and maintain the lunch jar?

The inner bowls are dishwasher-safe on top racks and microwaveable, making daily use straightforward. The stainless outer container has a nonstick interior coating that wipes clean; remove the plastic bowls before washing the jar to prevent damage to the vacuum seal.

• Removable bowls simplify washing and reheating.
• Nonstick-coated inner surface for easier cleaning of the steel container.
• Avoid submerging the outer vacuum container to protect insulation.
• BPA-free plastic parts for routine food-safe care.
