Yumbox is a kid-friendly, bento-style lunch container designed for kids and adults. Yumbox is made with high quality, super durable, BPA-free, food-safe materials. Read our Frequently Asked Questions (FAQs) below to learn more or contact us with questions.
Is Yumbox leakproof?
Yes. Yumbox is a leakproof container. Yumbox’s silicone lid engages with the tray to create a tight seal keeping food contents in place, including wet foods like yogurt and applesauce (not water). Foods will not leak between compartments or outside of the box.
How do I pack wet foods?
Yumbox is designed to hold wet foods but not liquids. To ensure that food stays in place and does not leak to other compartments, follow these 4 Easy Steps:
1) Do not overfill compartments (an overfilled compartment could cause another to leak as well);
2) Remove any excess liquid from canned fruit, applesauce and yogurts;
3) Keep contents cool by adding an ice pack to your lunch tote;
4) When closing Yumbox, press down on the lid with the palm of your hand and snap latch to closed position to create the best seal.
Do not pack yogurt drinks, soups or runny/watery dressings.
Do pack foods with the consistency of ranch dressing, ketchup, chunky salsas, hummus, yogurt, and veggie dips. These are all great options. Some oily vinaigrettes may leak out of the dip well. One trick that can help keep vinaigrettes in place is to dress the salad and top it with a few croutons. The croutons will absorb excess oil/liquid and keep the vinaigrette from seeping into a neighboring compartment. If you are not sure if your food choice is too liquidy to pack, we suggest that you conduct a quick test before sending your child to school with that food. Simply add the test food to a compartment, close Yumbox properly and give it a good shake (or leave it on its side for 10 min.). Set Yumbox back to normal position and open to see the results.
Is Yumbox dishwasher safe?
Yes, Yumbox is dishwasher safe. Top rack only. We highly recommend hand washing the outer shell and/or removing it before the heat dry cycle. Yumbox has been tested at temperature 65C/149F, 110 min. cycle. Yumbox is made with ABS (exterior box), Tritan (tray), and silicone (seal). Yumbox is designed with rounded edges and smooth surfaces to make hand washing easy.
Special Care instructions for the silicone seal: Please be sure to empty contents each day, hand wash with warm soapy water and thoroughly dry your Yumbox before storing. Also, if you live in a damp or humid environment, leave Yumbox ajar, not sealed when storing. If you pack oily foods regularly, coat with a baking soda paste once a week overnight to avoid build-up.

Is Yumbox food safe?
Yes. All materials are food-safe, BPA-Free, Phthalates-free and are CPSIA and FDA compliant.
Is Yumbox microwavable?
Yumbox's exterior shell is not microwave safe. We do not recommend microwaving the inner tray. Yumbox is designed for serving cold or room temperature foods. If foods that require reheating are being packed, we recommend using removable silicone cups.
Is Yumbox thermal?
No. Yumbox is not made with thermal materials. If adding food like yogurt, which should be kept cold, we recommend packing Yumbox in an insulated bag with an ice pack to keep contents cool.

Is Yumbox’s tray removable?
Yes. Yumbox’s tray fits snuggly in the bottom half of the exterior box. It can be removed easily for cleaning, packing or for at home use. In fact, kids love eating their meals out of Yumbox’s tray at home too! The first time you open Yumbox, you may find that the tray is slightly difficult to remove. After initial removal, it will return to its comfortably snug fit.
Are Yumbox’s trays interchangeable?
No. While the 6-compartment trays may fit in 4-compartment outer boxes, and vise versa, they will not create a seal and do not have a perfect fit to prevent leaking or spills.
Please note that the Yumbox Original 6-compartment is not compatible with the 2014 and earlier models. Please look at the photos of the trays if you aren't sure which one you own.
Can I pack a Yumbox lunch the night before and store it in the fridge?
Yes. Yumbox acts as an excellent storage container. The seal keeps foods fresh for days in the fridge.
