About this item

Product details

It’s the same OmieBox you know and love, but all grown up so your kids can continue to pack healthy & nutritious lunches for school. We designed OmieBox UP to better meet the needs of older kids! OmieBox UP is ideal for kids 9+ while OmieBox is better suited for ages 3 to 8.

BIGGER THERMOS -- built in THERMOS INSERT can pack 12 ounces of food (40% more than OmieBox). Food stays warm for up to 4 hours, making it easy to pack your kids’ favorite hot meals.
NEW! REMOVABLE ICE PACK -- For kids on the go, OmieBox UP has a removable ice pack that keeps lunch cool for hours. Now you can send hot soup and chilled strawberries without using a million small containers. OmieBox UP packs HOT & COLD TOGETHER in one compact bento box.
NEW! COOL DESIGN & COLORS -- new look & feel to reflect your kids growing independence and individualism.
HIGH QUALITY INVESTMENT - Durable, built to last and saves you the expense of buying a separate thermos! OmieBox UP uses 18/8, 304 grade stainless steel. It’s BPA-Free & Phthalate-free.
EASY TO CLEAN - OmieBox UP is dishwasher safe. The rubber seals are all removable, so you can wash it thoroughly everyday. If the seals get worn or damaged, you can purchase replacement seals instead of throwing the box out.
Recommended Age Grade- 9+ Years of Age
CAUTION: Use extreme caution when handling hot water or hot food.
Don’t leave food inside OmieBox UP for more than 12 hours.
Never put your thermos or OmieBox UP inside a microwave, on the stove top, or in any type of oven.
Never boil your thermos.
Always hand wash your thermos.
Food in the thermos could burn or scald the user. Use extreme caution and always test the temperature before consuming.
If the contents are left in the container for more than 24 hours, or if you think the food might be spoiled, use caution when opening the container. Point the opening away from the user and other persons to avoid injury.
Don’t store carbonated beverages or dry ice in your thermos.
Don’t put your OmieBox UP in the microwave or freezer.
Always use extreme caution when handling hot contents.
Do not fill the thermos past the ridge below the neck.
Do not over-tighten the thermos lid.
Hot content can cause pressure to build within the thermos resulting in a release of hot steam. Open with care to avoid burns.
Use extreme caution when opening a stuck thermos lid as the internal pressure might cause the lid to eject forcefully. Always point it away from people and pets to avoid injury. Contact us to get a warranty thermos replacement.

Worthy lunchbox investment

I have been searching for an amazing lunch box for my 9year old son! Love this lunch box because of it being able to keep warm and cold foot items together in one! If your looking to send your kiddo with both warm and cold foods this is great! Great investment that he will be able to use for the years!

My son loves it!

Of my 3 sons, one of them really enjoys a heated lunch. This year, we upgraded his lunchbox to the OmieBox Up, and he's a huge fan. He loves the “cool look” and I love that he can have hot and cold in the same box. He's 8 and isn't eating a TON at lunch, but I think this box should be able to grow with him.

Love the idea of this lunch box.

I do love the idea of this lunch box where you can switch between a thermal and just an empty space for just dry stuff or a sandwich! It does what its suppose to. So I am really glad i have this option.
