The Kilner Kids Jars are ideal for storing homemade baby food in glass rather than plastic. Ideal for batch cooking homemade healthy purees for babies or young children. Making your own allows you to control all the ingredients, especially sugar and salt levels. The easy, push-on silicone lids are airtight and leak-proof making them perfect to take on the go. The set includes three different color lids: purple, yellow, and turquoise along with adhesive labels to document the use-by date. These jars can be stored in the fridge and are suitable for microwave warming providing the contents are fully defrosted (adhering to the advice in the instruction leaflet). We advise handwashing the glass jar to preserve the decoration.
