NUK Baby Bottle, Winnie the Pooh Design Holds up to 300ml Nipple Size: M I fell in love with it and bought it, but my child preferred the "Mother's Touch" brand, so I rarely used it. The nipples are compatible with the "Mother's Touch" brand, so I used those instead, and never used the NUK nipples. The bottle has been washed, but due to the nature of plastic, there are some water spots. Thank you for your understanding as this is a used item.
