Willow wearable breast pump (Generation 3). Also includes three 24mm reusable milk containers, three 24mm flanges (one says compatible with 2.0 version), two 17mm flange inserts, two 19mm flange inserts, and a new power cable. I also will include a set of unopened 21mm reusable milk containers (not pictured). This version connects to the Willow app to track how much you are pumping per session. Pet free, smoke free home.
