About this item
A Warm Hug in a Lunch Box
There’s nothing better than a warm, home-cooked meal on a busy school day. Our Kids Food Jar makes it easy to pack their favorite soups, pasta, or chicken nuggets and keep them perfectly warm until lunchtime. It’s the perfect way to add variety to their meals and send a little comfort from home.
Designed for Independent Kids
No more struggling with tight lids! We designed the top with a unique, concave shape and an easy-grip texture, making it simple for small hands to twist open without needing a teacher's help. The wide mouth also makes it easy for them to eat from directly and simplifies filling and cleaning for you.
Built for Durability and Safety
Crafted from premium 18/8 stainless steel, this food jar is durable enough to handle daily drops and tumbles. The double-wall vacuum insulation provides superior temperature retention, and every part is 100% food-grade and BPA-free, so you can pack their meals with complete peace of mind.
Designs That Spark Joy
Lunchtime should be fun! That's why our food jars feature vibrant, artist-drawn characters with a unique 3D texture. It’s a fun and stylish look that perfectly matches their Bentoheaven water bottle and lunch bag.

Care and Use
- Pro-Tip for Maximum Warmth: To keep food warm for 4-6 hours, it's essential to pre-heat the jar. Simply fill it with boiling water for 5 minutes, carefully pour the water out, then add your piping hot food.
- Pro-Tip for Keeping Food Cold: For cold items like yogurt or fruit salad, pre-chill the jar by placing it in the freezer (without the lid) for 15 minutes before filling.
- Cleaning: To protect the 3D designs, hand washing is recommended. The wide mouth makes it easy to clean the inside thoroughly with a bottle brush.
- First Use: Like any new stainless steel product, you may notice a slight metallic scent initially. We recommend washing thoroughly with warm, soapy water before the first use.
- Safety Warning: Do not microwave. For safety, do not fill with overly hot food that could cause burns.

FAQs
How long will this jar really keep food warm?
With proper pre-heating (see our pro-tip above!), the jar is designed to keep food safely warm for 4-6 hours, perfect for the time between packing and a school lunch break. Performance can vary based on the food type and starting temperature.
Is 10 oz big enough for my child's lunch?
The 10 oz (300 ml) size is perfect for a main course for younger children (ages 3-6) or a hearty side dish (like soup or mac & cheese) for older kids. Many parents pair it with a bento box for snacks and fruit to create a full meal.
Is the lid difficult for a kindergartener to open on their own?
Not at all! We specifically designed the lid to be kid-friendly. The shape provides an easy grip, and it doesn't require excessive force to open, which helps build independence at lunchtime.
Does the jar come with a spoon?
This food jar does not include a spoon, allowing you to pair it with your child’s favorite utensils. Our matching Bentoheaven Kids Travel Utensil set is a perfect companion!
How do I get rid of the initial smell inside the container?
A thorough first wash with warm water and dish soap usually takes care of any manufacturing odors. For any lingering scent, a soak with a mixture of baking soda and water overnight is a great, safe way to neutralize it completely.
