Replacement Lids Compatible with Philips Avent Natural Baby Bottles, Extra Secure Leak-Proof Caps for Travel, BPA-Free, High-Toughness Protective Covers for Glass & Plastic Bottles, 4-Pack

These are the exact same as brand name. High quality, fit perfect and inexpensive.

These lids fit both my Philips Avent plastic and glass bottles perfectly. I prefer using these over the nipple and cap combo because it's so much easier—just pop the lid on and stick the bottle in the fridge. It feels cleaner and more convenient. Plus, no leaks when traveling, which is a huge win!

These worked great for storing milk in the fridge and for travel! They never leaked and were super easy to keep clean.

The rings are identical to the Avent brand. We were gifted some bottles but no rings so there were exactly what we needed.

I ordered these to store pumped milk in with avent natural bottles. While they do a great job for refrigerator storage, I'm not sure I would depend on these for travel storage as they aren't completely leak proof. Like I said, they're perfect for when I'd put milk into the fridge after pumping. However, sometimes when bagging leftover milk, I'd shake or swirl the bottle to get the fat off the edges, and I noticed a couple times that some milk seeped out the threads in the cap.

The best option for me to travel without leaks in the diaper bag

So great to have extra on hand! Fit perfectly on the advent bottles. We lose the tops so easily so it’s nice to have extra!

The caps that came with the bottles in their original packaging weren’t as hard to take off as these are. It takes me about 15 more seconds to wrestle the them off, and when you have a screaming baby next to you that can add to the stress of the situation. They work and don’t leak, which is all I care about in the end. But they will be harder to get off.
