Meet our flagship leakproof food storage system designed for large-portions, endless versatility with modular inserts and maximum functionality in the kitchen and beyond. Each of the five steel vessels 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 reinforced leakproof LFGB certified silicone lid.
