Insulated Lunch Bag 25x15cm with Flask Strap / Drawstring Tote / Blue & Plaid

*Upgraded from May 20, 2020, with a complimentary aluminum foil lid for enhanced insulation. Many insulated lunch bags on the market are made of plastic. We designed this specialized insulated bag for lunch boxes, crafted from cotton-linen fabric with padding and a double layer of aluminum foil insulation (most market bags only have a single layer). It's like wrapping your lunch box in a cozy blanket with an added thermal barrier. Unlike typical insulated lunch bags, this one features an inner lining that encloses the aluminum foil fabric. This design allows it to double as a stylish everyday tote, perfect for carrying anything you need. For added convenience, it includes a thoughtful strap design to prevent thermal flasks from tipping over. / Dimensions / Internal space approximately 25cm (bottom width) x 15cm (bottom depth) x 18cm (height, excluding drawstring fabric). Handle length: 36cm. The strap can secure thermal flasks with a diameter of 9-12cm. / Materials / We aimed to minimize plastic in our material selection, opting for: 100% cotton-linen outer fabric, polyester batting, double-layered aluminum foil bubble wrap, cotton-blend lining, cotton-blend handles, wax cord, and cord lock. / Care Instructions / Hand wash only; machine washing may cause deformation. Do not iron, as it can damage the insulating bubble layer.
