I have this lunchbox and thermos. It's is awesome!!! The thermos keep my coffee HOT not warm all through my 8-10 hours day. I add a few ice cube during hot summer day for my cold water. I kid you NOT, cold water all day. The cooler you have to be creative to maximize the spacing. I can fit a glass lock, a 17oz Stanley food jar and Thermos 16oz food jar. What more do u want? I pretty much have a lunch buffet inside my stanely cooler. This is me...I keep my fried rice in my glass lock. Soup in my Stanley food jar and fruits in my Thermos food jar. Hot coffee or cold water in my big thermos. All I can say, each time I use my stanely cooler and thermos, I'm saving $10-$15 everyday. Packing lunch have never been easier. I stop buying lunch. You know how HARD that is. It's like a smoker trying to quit smoking...lol. This is my story.
