MINMUNJIU 3 Pack Silicone Sleeves for Dr. Brown's Glass Baby Bottles, Anti Breakage Baby Bottle Holder with Handles for Baby Girls, Compatible with Dr. Brown's Glass Baby Bottle, 4 oz/120 mL

fits perfect

I would stick to the intended purpose. I used one on an 8 oz bottle, the plastic bottle, and it was a nightmare to get on. I'm not sure how easy it's gonna be to get it back off of this bottle because it is super tight. 😂 My assumption is, this is for the four ounce glass bottle, and I cannot imagine that this is going to be any easier to put on a glass bottle than the plastic one, but who knows it might work fine. Once I got it on there, it was in place and it's not going anywhere. The baby can't pull it off. And once the bottle gets filled, that bottle's not sliding around anywhere, the silicone is gonna keep it in place. So, I have to say, they are super cute. I like the little design on it and they seem well made and they're perfect for baby's small hands. It's going to make it easy for the baby to use both hands instead of one to hold their bottle. I don't think that I would keep them on when I go to wash the bottles because water is going to get in there and cause mold to set in. The backside where it has that big cutout circle is not tight, so you're definitely gonna get water inside. I would still recommend them because I think they're very handy for keeping bottles from sliding around and making it easy for small hands to hold and the design on them is super cute.

This bottle sleeve is super cute and helps with grip and break protection. The only reason I gave 4 stars is that getting them on the first time took quite the effort. I had to get a second set of hands to help me. But once they’re on, they stay put and clean up well. I honestly love these sleeves because they help keep bottles from slipping out of my LO's hands and smacking her in the face.

These are great for teaching babies to start holding their own bottle. The they might be a good option to help transition out of bottles while not buying all new bottles all at once. They seem easy to clean and durable. Don’t really have complaints about them so far.

Good sleeves but they are a bit tight. It feels like wearing really tight jeans and once it's on, it's not rigid, it's too soft. Wish they made gave it a bit of a thickness and less silicone yet soft, that would've been a good combo. Good set though makes it easy for baby to hold bottle on their own.
