6pcs Replacement Bottle Nipple Collars Rings for Dr. Brown’s Narrow Plastic & Glass Bottles
These nipple collar rings fits our Dr. Brown’s 4oz narrow glass bottles. The threading lines up well, and they screw on securely without any leaking issues. Quality is comparable to the original rings that come with the bottles. They hold the nipples firmly in place and create a good seal. I haven’t experienced spills or messes during feeding. I also like that they are BPA-free. I like having these extra rings on hand. It is convenient, especially when some are in the dishwasher. This set is a great value, works exactly as intended.

Bottle collar replacements
Fits our Dr. Bottle bottles like originals. No leaks from the nipples. They are easy to clean. Quality of material looks decent. They are visibly different from original but look fine. Pack comes with six but for this price, I think I’d just buy a pack of new bottles that come with the entire assembly which you can find in packs of 2 or 3. They work if you need a collar replacement but not a great value.

Fit perfectly on my Doc Brown Bottles with no leakage
These bottle collars fit my Doc Brown Bottles perfectly (definitely compatible!) and function just as well. They are just as easy to put on and wash as the originals and don’t leak at all. I put water in the bottle when first trying it out and shook the bottle all around and didn’t have any issues with leaking. I’ve also used with milk when feeding my baby several times now and haven’t had any leaking. I trust traveling with it. I personally like the little wave like design on them. My only complaint is the price and that’s where I took away a star. For this price, I’d expect there to be nipples that also came with it.
