Used from June to October of this year. It's a Medela manual breast pump and Medela breast milk bottles. 【Freeze and Refrigerate Directly】After expressing milk, you can close the lid and store the breast milk in the freezer or refrigerator. 【One Container is OK】It can be attached to all Medela breast pumps. Attach the Calma nipple and you can feed directly! You can express, store, freeze, and feed breast milk all in one. 【Easy to Clean】The breast milk bottles can be washed in the dishwasher and sterilized in the microwave. Made with BPA-free materials. 【Safe Materials for Both Baby and Mother】Made with safe, BPA-free materials, it's durable and won't break or shatter if dropped. 【Easy-to-Read Graduations】Features colorful ounce and millimeter markings, making it easy to measure the amount of expressed breast milk. Includes 3 bottles sold separately, 1 bottle attached to the breast pump, lids, and new valves. The breast pump has been used to a certain extent (I don't know which bottle is which), but the bottles are plentiful and I think they are mostly clean.
