Made of cotton Measures 9.75 x 7.5 x 3.5 inches Holds most pre-packaged frozen meals or Thermos(R) Slip pocket and a large zippered opening, plus an ID window Details: Here's a much prettier lunch bag than a brown paper bag! With enough space for most pre-packaged frozen meals and a handy ID window to set your bag apart from the rest, you'll never go back to a boring lunch bag. There is a call out inside the lunch box.
