Our original three-piece bamboo lid kit is the perfect addition to the 8-cup Adventure X stainless steel container set to lock in liquids. The silicone seal prevents spills and keeps food separated on the inside when reVessel one and two cup inserts are used and ensures that no dressings or sauces leak out into your bag or clothing. The bamboo lid offers the bonus of having a cutting board and tray conveniently integrated to quickly chop or serve food wherever you are. With this lunchbox configuration, you can confidently carry up to six 1-cup inserts or three 2-cup inserts in your compact kit. As always, with reVessel designs, no food will come into contact with plastic.
