6pcs Replacement Collar Rings for Medela Baby Bottles 5oz & 8oz | 1 Count (Pack of 6) BPA Free | Compatible with Plastic & Glass Bottles | Mess Free No Leak or Spill

These replacement collar rings are exactly what every Medela bottle user needs. I got the 6-pack for my baby’s 5oz and 8oz bottles, and they’ve been working perfectly with both the plastic and glass versions. The fit is snug and secure — no leaks, no unexpected spills, and definitely no more guessing whether it's screwed on tightly enough. What I love most is the quality. They’re BPA-free, durable, and feel just as sturdy as the original Medela parts. After several washes (both by hand and in the dishwasher), they haven’t warped or cracked, which gives me peace of mind when prepping bottles in advance. This pack saved me from having to replace whole bottles just because of a worn or missing collar. Whether you're replacing old parts or just need extras for daycare, these are a reliable and budget-friendly solution. Highly recommend for any Medela bottle user who wants a mess-free, no-hassle feeding experience.

Arrived on time and great quality.

Having the replacements available saves us money. This is a great deal.

Good quality! No leakage! Just a note, there are two different sizes of medela nipples and these are the wider base ones.

Love them! They work great with the medela bottles. It's nice having spares of the collars to keep in the rotation. Can't tell the difference when using them which is great. I recommend them! Especially since you cannot but just collars straight from medela themselves.

CONS: -Pricing -Fit Medela definitely makes a profit off of their products like this by only offering pieces, not everything you need together. I bought their bottles, which come with CAPS, not rings nor nipples. Then I have to buy the nipples and rings separately, and they are ridiculously expensive for just these individual pieces. Unfortunately, the nipples for Medela are the only ones that really fit well without leaking for these replacement collars. If you are looking for the just-slightly-smaller collars to fit with the other silicone nipples for Dr. Brown's or Similac's or Nuss (I think that's the brand), then do NOT buy this collar. Yes, it will work, but because of the minuscule size difference, there will likely be leakage when you use them/turn them upside down. PROs: -Quality If you have the actual Medela bottles, rings, and collars altogether, THEN this ends up being a good product. Again, I had to buy all of them separately to find this out. I even tried other nipples with these collars that are not from the Medela brand but are supposed to be the same size, and they will leak when I combine them with these collars on the Medela bottles.

Why did you pick this product vs others?: Suit to naps.

Fit my medela bottles just fine, good price
