Thermos® King Food Flask 3 "On the small side" Katrina 11 September 2014 Disappointed that this standard size thermos was so small. Certainly not big enough to satisfy my 10 year old's lunch appetite. As previous reviewer said - fine for a portion of soup. Otherwise very functional and solid but crucially not dishwasher safe ... A note from the team Thanks for placing your review. We're sorry that you feel the flask is too small and will be in touch shortly.
