Here at Unimom we care about our customers and want to
provide the best support at all stages of the breastfeeding
journey. As a way of contributing to your breastfeeding
success,one complimentary set of flanges/breast shields. If your Z2
breast pump did not include the breast shield sizes you
need, we are happy to send you a pair. This is limited to
new pumpers who have just received their Z2 and require a
larger or smaller size other than the included 21mm or 24mm
sizes. Please note that it is helpful to measure yourself to
get a more accurate size, as we can only send a single
complementary pair.
