This food storage container set includes 2 food jars 0.75l - 1.5l and 1 bottle 1l in extra-clear hygienic borosilicate glass which is extremely strong and highly resistant to thermal shocks. It is a very safe and neutral material for food storage since its chemical composition will not affect the acidity level of any liquid or food it contains. The containers can be stored in the fridge and freezer and used in the microwave for re-heating or de-frosting, after removal of the stainless steel clamp. The closure with clamp and rubber seals provides an airtight interior and makes them fit for preserving food in a healthy way without additives, by heat treatment, in oil, vinegar or brine or pickled. Thanks to their attractive designs these jars will look good on any tabletop.
