Take your lunch everywhere with you, while showing your Slytherin pride at the same time. This insulated lunch bag will keep your lunch warm (or cold) and is easy to carry around thanks to its handle. It will also open very easily thanks to its velcro closure and the pocket on the side will allow you to easily slip in an extra treat or water bottle.
