OmieBox review

The OmieBox is the pick for kids who want soup, pasta or nuggets warm at lunch. OmieLife builds an insulated 8.5 oz thermos into the bento, so hot food sits next to separate cold compartments, and the whole box holds 47 oz in an 8.5 x 7.5 x 3 in. body that weighs 1.7 lbs. Materials are 18/8 304 grade stainless steel, food grade plastic and silicone, and the company states the box is BPA-free and phthalate-free and FDA, CPSIA and CPSA compliant. It is designed for ages 3 to 7, with the OmieBox UP sold for kids 9 and up. The tradeoffs are care and price: OmieLife recommends hand washing, says not to microwave it or boil the thermos, and rates the side compartments leak-proof only up to 1 teaspoon of liquid. At $49.95 it costs $20 more than the Bentgo Kids Lunch Box, and a backorder notice was showing when we checked. We compared documented features and published prices and did not test it.
