These small pots are Advent regards me really perfect, I use the Philips Avent brand since the birth of my child. They are used for freezing portions when preparing food in more than sufficient quantities to appetite small. It is easy to put the freezer, the microwave as they have no metal parts; they are easy to clean, It is a perfect product like all Philips Avent products and the price on Amazon is really very affordable. I highly recommend its purchase.
