I used this for follow-up milk, but my baby mostly refused it, so I washed it and stored it after sterilizing it in the microwave. This is the product before the renewal (see image 4). It has been used a few times, so please understand that it is a used item. 《Price is not negotiable》 ◆ I will pack it with the nipple part pushed in, as shown in image 3. ◆ Please check the images carefully before purchasing. ◆ This item will be delivered as is, so please ask any questions you may have before purchasing. ◆ Please refrain from canceling after shipping. ◆ I will use recycled materials for packaging. ◆ I will ship via Yu-packet Post Mini (no bubble wrap, simple packaging). ◆ Please refrain from purchasing if you are sensitive to used items. 《Please also take a look at my profile》
