With flexible, easy push-through bases and leak-proof hinged lids, parents can pop out frozen food or thaw/defrost and serve little one directly from the pot. Each pot provides one large 170ml portion which can be placed in the fridge or freezer and then straight into the microwave. The four large pots click together for easy filling. The marker pen included enables them to write on the pot to make for easy detection of frozen food! Also available in small size for stage 1.
