Paper Sack Lunch CoolerOur nostalgic nod to the classic paper lunch bag but with a modern twist. This best selling reusable, insulated lunch bag helps you ditch disposables and keep your lunch fresh through morning commutes or extra long lectures. We dont recommend placing loose ice directly in the bags. For best results, use reusable ice packs or sealed baggies, as the coolers arent designed to hold liquids.
