BPA-FREE MATERIAL: Made from 304 stainless steel, a widely-used food-grade material, our bento box ensures that no odors or negative effects will affect your food. The external structure is crafted with high-strength plastic, offering not only durability but also convenient storage capabilities. CREATIVE DESIGN: Our adorable lunch box features an anti-slip bottom, a stainless steel food container, a leak-proof cover, and an independent sauce bowl. With its vibrant contrast color design, this lunch box is the perfect choice for both adults and kids. EASY TO STORE: Measuring at a compact size of 3.38" x 9" x 6.5", our lightweight bento box can easily be stored in a handbag or bag. Its generous capacity of 1000 ml/34 oz is highly practical for everyday use. EASY TO CLEAN: This bento box is dishwasher safe; however, we recommend hand washing to prevent any deformations caused by pressure washing. NOTE: For liquid food, please use the sauce bowl as our stainless steel lunch box's three compartments may not have excellent leak-proof performance. Please do not microwave the stainless steel lunch box. We highly recommend using this lunch box for carrying food at room temperature.
