Philips Avent My Penguin Cup Replacement Soft Spouts, BPA-Free

These nipples are great to help transition my 1 year old to sippy cup. they fit perfectly with my avent natural bottles

I was happy to see that these fit the advent glass bottles because I can’t find glass sippie cups

Fits the cup perfectly but they are not leak proof.

The ones I received don’t look like what is pictured and they don’t fit the avent bottles
