Philips AVENT microwave steam steriliser bags are ideal for sterilising baby's feeding equipment, breast pumps and breast shields, and are convenient to use both at home and when out and about. Coming in a pack of five bags, each bag can be used 20 times, giving this pack 100 uses in total, and the bags also have a handy check box area for parents to keep track of usage. The bags also feature a window to allow them to quickly check on the contents, while a Safe Zone on each bag allows parents to remove the bags from the microwave with minimal risk of burns. Simply pour 60ml of water into the bag and add up to three bottles, or one breast pump. Easy to use for quick and effective sterilising.
