Used but still in great condition! I don't have the original bottles but do have the original connectors and tubing with a second tubing that has been modified to use with other connectors and bottles to make it easier to use. the modified tubing and connectors can be used with any medela bottles or similar bottles with same size bottle opening. Also added a clip to the back to be able to clip to pumping bra or pants but it can easily be taken off. Pictures show original tubing and my modified tubing as well as how the modified tubing is used. I have the original bag but no box. Open to reasonable offers!
