Dr Browns 2 Replacement Vent Reservoirs

These replacement Vent Reservoirs are exclusively for the WIDE-NECK 8 oz / 240 ml Dr Browns™ baby bottle . These are the same pieces that come on each Dr Browns™ 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 Browns™ Patented Internal Vent System , which allows our bottles to work differently .
