Playtex ULTRASEAL Disposable Baby Bottle Liners 4oz

I much prefer these original liners compared to the drop ins. They are hard to find but worth it. They take up less space in the kitchen and the trash, plus they never leak. Drop ins *always* end up leaking. You can also freeze breastmilk in them. Too bad they discontinued the playtex nurser bottles... they really were the best. I'll be hanging on to mine and buying these original liners till it's no longer possible!

The bags will leak in bottles made for the drop in liners but if you put a drop in liner in first or at least the top of the drop in liner and then the put in the bag it won’t leak and the bags are usable. And they are cheaper then buying resale liners!

Bought these for my new grandbaby. Momma loves the convenience. Works well.

Great for new mother and baby.

These are not worth the money. They do not fit the 4 Oz bottle. I have lost so much breast milk trying to use these.

I used to use these liners with the old version of the Playtex bottles. I absolutely loved them then, and I love using them now with my grandbaby just as much. I prefer these liners over the disposable drop in liners (but both types of disposable liners they offer are a great option). I highly recommend purchasing these! These liners seem to collapse the best out of all the options of liners Playtex Baby offers. I definitely prefer these over the reusable silicone drop in liners. Their reusable silicone liners don't collapse as well and therefore don't get and also don't keep air out of the bottle anywhere near as well.

These are super easy to use and helped cut back on all the bottles I had to sterilize. I think this style works way better than the drop in bottle liners. In my opinion. My daughter was a premie and also helped with the amount of air she was getting in her tummy. I think these definitely helped with how much she was spitting up.

Since it’s almost impossible to find the playtex drop in bottles I was hoping to find something else that these would work with. The MAM 5oz bottles work perfect with these, I don’t even need to add the bottom of the bottle back on if I don’t feel like it. Hoping this helps someone else out! Had to test it out myself because I hadn’t seen anyone else try it that way. It works, it’s worth it!
