Philips Avent Natural Response Baby Bottle Nipples 4-pack Size 2

We got 4-pack Philips Avent Natural Baby Bottles with size 2 (Slow flow) nipples thinking it would best to start. Our little guy needed faster flow right away so switched to 3. Condition : 3 new nipples and one of them used once for testing. Priced accordingly, Retail : 15 plus and tax. I’m open to swapping with same brand nipples flow 3/4/5. Pickup at Trafalgar Public School. It’s available unless it’s mark other wise. Thank you.
