Dr.Brown Nipple Level 3 (6m+)

A pair of Dr.Brown Narrow Nipple in size Level 3 for 6months+ babies. I had ordered Level 2 from Amazon, but the seller dispatched Level 3 and wouldn't take return. Since it's non-returnable and I don't plan on using it for my baby, I'd like to sell it to someone who might need it. It is sealed and unopened.
