Promotional Black+Blum 6.7L insulated Lunch/Cooler Bag This 6.7L insulated lunch bag is made from recycled PET, such as used plastic bottles, and offers plenty of space for everything you need to get through the day—whether it’s a lunch box, water bottle, fruit, or snacks. It’s the ideal insulated lunch bag for both kids and adults, and it’s now available in four colours with matching tote bags. Inspired by the design of dry bags, the roll-top closure and welded lining make the bag 100% leak proof when stored upright. The insulated interior helps maintain the temperature of the contents, keeping everything nice and cool. The food-safe and water-repellent inner surface is easy to wipe clean, and the roll-top design makes it simple to carry, compress, or attach to another bag or even your bicycle handlebars.
