Philips Avent Tempo Bottle Liners 8 oz SCF138/05
From the Manufacturer
The AVENT Tempo 8 oz. Wide Pre-Formed Liners work with the AVENT Tempo Natural Feeding Nurser to promote healthy active feeding. Because baby controls milk flow, it's more like breastfeeding, which helps reduce the risk of overeating, spit-up and colic. Strong, pre-sterilized Tempo Liners are easier to fill than standard brands, and manufactured to hold precisely 8 oz. At home or away, day or night, now you have the convenience of a sterile bottle whenever you need it.
