Dr. Brown's Vent Reservoirs Description
For Standard 8 oz/240 ml Dr. Brown's Baby Bottles
• 8 oz/240 ml Dr. Brown's Standard bottle
These replacement Vent Reservoirs are exclusively for the Standard 8 oz/240 ml Dr. Brown's baby bottle. These are the same pieces that come on each Dr. Brown's bottle and are meant to replace worn or lost parts. Along with the vent Insert, the Vent Reservoir is an integral part of the Dr. Brown's Patented Internal Vent System, which allows the bottles to work differently.
