Open and seal tightly with just one hand: these are the practical fresh & easy storage containers from Leifheit. They are recognizable by their elegant design and the red ring of the patented one-handed operation. To open, simply flip the ring up. To close, place the lid on, fold the ring down, and everything is sealed airtight and watertight. Due to their square shape, the fresh & easy storage containers are easy to stack, saving space in your cupboard and pantry while keeping things organized. Capacity is 1,600 ml. The decorative containers are also available in four additional sizes: 400 ml, 800 ml, 1,000 ml, and 1,200 ml.
