Stainless Steel Leak-Resistant Lunch Box The perfect lunch box for storing a waste-free lunch from home while on the go. This rectangular stainless steel lunch box has a handy silicone seal around the inside of the lid which means it's more leak resistant than standard containers. Its levered locking clips at each end provide extra pressure during closure. MATERIALS Made responsibly in India from high quality 201 food-grade stainless steel. Free from BPA, phthalates and lead. CARE GUIDELINES The silicone seal is removable and can be washed separately, then reinserted, flat side down.  Please make sure that the seal and container lid is clean, dry and free from grease before re-inserting. A spare seal is also included inside the container. Please do not put your Adoni lunchbox in the microwave. It is 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 correctly after. SIZE Overall dimensions approximately: 4.5cm x 18cm x 13cm.Internal dimensions approximately: 4cm x 15.8cm x 12.3cm. 675ml capacity.
