I have a Lansinoh Affinity double electric pump in used, excellent condition.  I take great care of all my items. This pump works very well for the purpose needed. I have included a description of the item, in the pictures, which will give you the information needed. I also have 16 unused storage fridge/freezer bags as well as 10 small bottle storage containers. I do have an extra White valve, as I purchased an extra one. Feel free to ask any questions. Asking $50.00 but will be open to best reasonable offers.
