Make lunch time fun with the Thermos FUNtainer My Little Pony 10oz Food Jar. Thermos vacuum insulation technology virtually eliminates temperature change within the beverage container by creating an airless space between two stainless steel walls. The result is an insulation layer that performs better than any other. A superior insulated container you can depend on to keep your child’s food hot or cold for longer. This food jar keeps food cold up to 7 hours and hot for 5 hours. Constructed with double wall stainless steel, this 10 ounce food jar is built to withstand the demands of everyday use with its durable stainless steel interior and exterior and features a wide mouth that is easy to fill, serve from and clean. In order to maximize the incredible insulation technology, it is recommended to pre-chill or pre-heat the jar just prior to use. COLOR: Purple. DIMENSIONS: 3.5"Lx3.5"Wx 4.5"H.
