DOUBLE LAYER LUNCH BAG: Experience the convenience of our spacious double-layer lunch bag, measuring 9.04" x 5.9" x 7.86". The design allows for efficient organization, separating different foods in the upper and lower compartments to prevent mixing. The removable second layer enhances versatility, while the main zippered compartment keeps your meals and beverages hot, cold, or fresh. This lunch bag accommodates all your essentials, including snacks, drinks, sandwiches, fruits, and a thermos. SUPERIOR MATERIAL: Crafted with flannel cotton on the outside and high-quality PVC insulation on the inside, this lunch bag ensures optimal temperature retention. Unlike traditional aluminum film, our reusable PVC material maintains food freshness for hours, making it ideal for meals on-the-go, picnics, road trips, and office lunches. LEAKPROOF & EASY TO CLEAN: Featuring ultra-thick PVC soft lining with hot-welded seams, this lunch bag is leakproof and prevents spills. Cleaning is hassle-free; simply wipe away any mess with a damp cloth or napkin. MULTI-FUNCTIONAL DESIGN & STYLISH: Our lunch bag combines functionality with a stylish flannel cotton exterior, making it suitable for everyone—men, women, and children. Available in vibrant colors, it can be carried by hand or over the shoulder, serving as a lunch cooler, shopping bag, picnic bag, or even a makeup bag. LARGE OPENING FOR EASY ACCESS: The insulated lunch bag is equipped with high-quality metal SBS double zippers for smooth operation. The wide mouth design allows for easy access to contents, and the second layer features a convenient side opening for effortless packing and retrieval.
