b.box Step Up Sippy Cup Pack Teat Only (Cross-cut nipple and cap) This item was received as a baby shower gift in 2024, but I have no plans to use the nipple and sippy cup parts, so I am selling them. Although unused, the item has been opened and stored in a zip-lock bag. Please refrain from purchasing if you are concerned. Please check the condition of the product in the photos before purchasing. I plan to wrap the item in packing material and ship it via regular mail. Thank you for looking.
