Your pocketbook will benefit from packing lunches instead of going out, and your personal trainer will appreciate that homemade food is usually healthier. Kids will love the fun colors and momma earth will thank you for not using disposable junk that ends up in a landfill. These colorful 10oz insulated food jars are a win, win, win, win situation! Foam insulation keeps food hot or cold for up to 4 hours, and the durable plastic will not break (contains no glass). The lid even holds a spoon and fork combo for added convenience!
