Dimensions: 8.5” x 7.5” x 3” Box volume: 47 oz., Thermos volume: 8.5 oz. Materials: 18/8 304 grade stainless steel, food grade plastic & silicon Redesigned OmieBox Features Our redesigned OmieBox is the bento you know and love with these improved features: 30% Bigger Thermos: now 8.5 oz (6.5 oz before) Better Insulation: thermos keeps food warmer, longer. Easy To Open and Close: the sealing system is completely redesigned so the seal sits on the bottom tray instead of the top lid. This makes the lid super easy to open - kids can do it with one hand. The seal is also much easier to disassemble for cleaning. Updated Colors: same 5 colors, but updated for a more modern feel. The SKU and UPC codes remain the same. Other Differences Additional differences to be aware of include: The thermos lid can now be screwed into the thermos directly, without the securing insert (the square piece). Whereas the thermos lid and securing insert were sold together previously, they will be sold separately from now on. There is a small hole near the handle. This hole houses a microscopic GORE-TEX membrane which prevents trapped air from deforming OmieBox. The membrane only works in 1 direction, so while air can pass, it will not allow water or debris to enter OmieBox. Please do not try to poke the hole with sharp objects as this will damage the membrane. The box does not come with the lid seal installed. The lid seal will be packed in a polybag and placed in the long compartment along with installation directions. Customers will need to clean the lid seal and install before using their redesigned OmieBox for the first time. The round thermos lid gasket comes in only 1 color (clear) The hot water and harsh detergents used in a dishwasher will cause some sensitive dimensions of the redesigned OmieBox to warp, therefore making the box no longer leakproof. We are very clear about this in the user instructions. If a customer accidentally puts OmieBox in the dishwasher it shouldn't cause any issues in the short term. However, we strongly recommend handwashing. Leaking caused by dishwasher use is not covered by warranty.
