Battery and mains operated so you have the flexibility of moving around or relaxing in one place. I have included lots of extras. 2 x 21mm soft flanges as stated above. Lansinoh breast pads and milk storage bags.Also added a new box of tommee tippee closer to nature milk sachet bags. All the instructions and manuals are in the box! Madela you won't be disappointed, by far the best electric pump I've ever used.
From a good home, pet and smoke free! Any questions please feel free to ask.
