Stainless Steel, Leak Proof Lunch Box Ideal for taking a waste free 'on-the-go' balanced lunch from home, this rectangular stainless steel lunch box has a handy silicone seal around the inside of the lid which means it more leak resistant than the standard A Slice of Green containers. It also has levered locking clips at each end for extra pressure during closure. Please note that although this leak proof lunch box is suitable for wetter foods such as dressed salad or dips it is not designed for liquid foods such as soups and broths. We recommend a screw top food jar for liquid foods. Made responsibly in India from high quality 201 food grade stainless steel. Free from BPA, phthalates and lead. The silicone seal is removable and can be washed separately, then reinserted, flat side down. Please ensure seal and container lid is clean, dry and free from grease before re-inserting. A spare seal is also included inside the container. Not for use in microwave. Dishwasher safe. We do not recommend the leak-resistant lunch boxes for use in the oven, even with the seal removed. Prolonged exposure to very hot temperatures can cause the metal to distort and then there could be issues with the lid fitting properly. Overall dimensions approximately: 4.5cm x 18cm x 13cm. Internal dimensions approximately: 4cm x 15.8cm x 12.3cm. 675ml capacity.
