Meet our flagship leakproof food storage system designed for large-portions, endless versatility now available with silicone modular inserts to achieve maximum functionality in the kitchen and beyond. Each of the four silicone inserts is microwave safe, while silicone and steel is oven, freezer and dishwasher safe and when combined with the integrated bamboo lid kit, it keeps foods from mixing on the inside and prevents spills in a bag or backpack. When not being used as a lunchbox, the all-in-one set can easily be used to prep, cook and store meals sealed with each universal reinforced leakproof LFGB certified silicone lid.
