Because of the air- and watertight sealing meat, fish, vegetables or fruit stay fresh and aromatic longer - without any preservatives. The tins are suitable for all Leifheit vacuuming devices. They are also dishwasher safe, microwaveable and freezer safe. Especially practical: they can be stacked on top of each other for easy storage. For better organization and control, they have a date display. To open the can, the vacuum can be easily released via a valve. The set includes three vacuum fresh holding cans in different sizes: 500 ml, 800 ml and 1400 ml as well as an adapter compatible with all Leifheit vacuuming devices. Of course, these are free of harmful BPA.
