This vacuum food storage container set from Leifheit keeps food fresher for longer without preservatives. Airtight and watertight sealing means that meat, fish, vegetables, or fruit stay fresh and flavourful for a longer period. The containers are electrically vacuumed in just a few seconds with the vacuum tube included in the set. The containers are suitable for all Leifheit vacuum sealing devices and particularly ideal for pressure-sensitive foods, liquids, or very moist dishes. The vacuum-sealed containers are also freezer safe, protecting the contents from freezer burn and retaining flavours and nutrients. The storage containers are microwaveable as the contents can be thawed or heated easily. The lid should be removed for microwave use. Open it with the integrated valve. Another practical feature is that the vacuum storage containers are dishwasher safe, making them easy to clean. The containers are stackable so that they can be stored easily to save space. The lid has a date indicator to assist with food storage organisation to know exactly when you last vacuum-sealed which food.
