Love this product so much, why does anyone buy regular baby bottles? These nipples as part of the Mason bottle system greatly reduce the baby clutter and single use baby items.

Makes it so easy to go from milk storage to bottle. We are loving this product!

I’ll be buying these vs the metal ring models for our travel days anyways. No chance of lost caps or missing them. They’re a bit bulkier in baby’s face but he doesn’t seem to mind. These are better suited for use with the silicone sleeves without handles bc then it just adds more and more bulk. These seem to seal better 100% of the time whereas with the metal rings, we do have some issues sometimes. Be sure not to overtighten, the plastic is not as strong as the metal and may crack. Anyways, loving these and especially for leaving the house these have become our go to!

I started using the metal l mason jar rings, but they started resting so I switched to these plastic rings and they are much easier to screw on the jars than the metal ones! The only downside is, I dropped a bottle and the ring broke fairly easy… Other than that I love them!

it’s a great solution for traveling with nipples. cap can get in the way but not too bd
