Screw Lids Aka Travel Caps with Rewritable Sealing Disc Compatible with Avent Bottle, Maymom Wide Mouth Bottles; Cap Replace Avent Natural Bottle Sealing Ring and Sealing Disc, 6pcs. (Blue)

Perfect design for glass avent bottles. Used mostly for traveling with breastmilk. Tight seal, no leakage. Like how it came in a 6 pack. Also good to store water in bottles that need formula.

Work PERFECTLY with Phillips Avent bottles. I tested out Evenflo wide nipples, lansinoh and mam and each of those fit perfectly with no leaking. Will be buying more of these

I love these for my Phillips avent bottles for storage! They do not leak. They screw on correctly

We use these on our Phillips Avent bottles and Pigeon nipples. Baby boy prefers and does better with the flow from Pigeon nipples but we like the glass bottles from Phillips (I know pigeon has glass too but we were given Phillips already). They are the perfect match for what we need. I like that it has the little caps to help keep the bottles clean when not in use. Shoutout to everyone who already reviewed the Avent-Pigeon compatibility! That really helped this first time mama!

They work perfectly for bottles I’m sealing breast milk for on the go ! Great price and they fit the avent bottles nicely.

Fit the plastic ones well but not the glass bottles, else they do the job

These are THE BEST. First, they don’t leak. I also love being able to write on them. My daughter is fed 100% by donor breast milk so every night I thaw enough milk for the next day. I love being able to number them because sometimes she doesn’t finish what I thawed for that day so I can make sure the milk that has been thawed the longest is her first bottle the next day. These are great. I also love that I don’t have to carry separate nipples, rings, and valves. I only have to carry nipples and valves because these rings work perfect when the bottle is in use. I have a 7-month-old and I’m 8 weeks pregnant so it’s going to be nice to be able to separate the babies’ bottles. These are so simple but PERFECT for what I need! Thank you, thank you, thank you!!!! ADVICE FOR USE: make sure the caps are completely dry before trying to write on them. They will not work if they’re wet, even if it’s just condensation. Also, use a run-of-the-mill, cheap, BLACK ball point pen, the ones that almost seem to write in a dark gray instead of actually black. They will erase the best. I’ve tried green and blue ball point pens and those colors seem to seep into the cap and stain it easier. (I’ve used blue a lot and in my pictures you can see the stains.) Lastly, rub the ink off the cap BEFORE getting it wet in dish water. The water seems to somehow set the ink. It’ll still rub off but not nearly as well or as easily.

Much better than buying a million bottles to try out. Work great, easy to clean in dishwasher. I use them to put mam nipples on glass Phillips avent bottles!
