This is a Pigeon breast pump. I received it from an acquaintance who didn't use it much, but it's a slightly older model and doesn't have the instructions or box. I looked up how to use the current series online and it worked without any problems! I'm including a breast milk freezer bag adapter and 4 Milton sterilizing tablets (expires June 2027). I've washed the parts that can be washed and then sterilized them with Milton. There may be some minor scratches, but I don't think it will affect use. Please ask if you have any questions! I didn't think I would need a breast pump, but I unexpectedly had to be hospitalized, and the breast pump was very helpful! I will ship it via either Yu-Yu Mercari Bin or Rakuraku Mercari Bin.
