With the food container set, you do not need any more plastic bags. Simply use these large food storage containers to keep meat, fish, vegetables, fruit, as well as cooked dishes fresh for a longer time. The set consists of two 1100 ml food storage containers made of glass that can withstand temperatures as high as 200°C. Since they are compatible with the Princess vacuum sealer set, you can remove the air from your glass food storage containers before freezing or refrigeration. This is the ideal solution to store up more food in a sustainable way! Note: This is an extension for the handheld vacuum sealer set.
