Dr. Brown's Natural Flow Options+ Glass Baby Bottle Sleeves,100% Silicone,4 oz,Narrow,Glow in the Dark

i didn't like it and we don't use it, it's very hard to install it on a bottle

these functional bottle sleeves glow in the dark which is great for night time feeds. helps me when i drop the glass bottles (whoops!) increasing the durability of the bottles. easy to clean, durable, perfect fit for the dr browns 4 oz narrow bottles, easy to use just slip it right on. also provides good grip for baby to hold.

Obviously they fit and do what they are meant to do, protect the bottle. I appreciate the thoughtful design with the window to see the oz/ml level. It's easier to get them on and off than the instructions would have you believe. I did not need soap to slip it on or off. I can do without anything or worse case a little water does the trick. I particularly appreciate the glow in the dark property of the blue swirl sleeve... for making bottles or using them in the middle of the night with the lights low or off, this is excellent. It is not much glow, very subtle, but just enough for me to see it and that's all I need.

Snug fit to the dr brown glass bottles. Needs to be wet to easily take off or turn, but when it dries it doesn't budge. Also is a plus that it glows in the dark

Good for glass baby bottles.

So I purchased this maybe 2 months ago and I actually love that it protects the glass bottles from breaking but I ordered this specific color cause it said it was glow in the dark, I’ve tested it out and it doesn’t glow! I could of ordered the pink one instead if that was the case. Overall I’ll rate it as a 4!!
