Medela Breastmilk Collection and Storage Bottles 8oz (250ml) - 8 Each

Love these, they hold about 9.5 ounces total, they are thin plastic but it’s nice and strong! They fit the medela pumps and I’ve used Zomee wide to narrow neck adapters and it worked great. These are 100% leak proof I swear by them!

Individually packaged storage bottles. Great for when we had a day trip that these were all ready and sterilized in their own bags. When I was done pumping, I just poured the milk right in the sterile bottle and put in my cooler. A little hard to read because the numbers are engraved into the bottle verses printed on, but I don’t have to worry about the numbers fading away. I would say the bottle could hold about 10oz to the neck of the bottle unlike the dr. Browns could hold about 11oz to the neck of the bottle.

I love having these bottles for mixing up formula and pouring breastmilk into when I was pumping. The ounce markers on the side are really helpful and they attach to most breast pumps! Worth it to have a set on hand!

Honestly loves my 5 oz bottles that came with my medela pumping kit but quickly realized that I was producing too much a day to be able to have clean bottles all the time in the fridge. The plastic is as thick as regular baby bottles so they are durable. They don't have a smell at all in my opinion and they fit onto my pumping kit. Definitely recommend even if you don't have the kit!

Works with your Medela rings and nipples.

I use the Medela pumps and these are great. They hold like 9.5 oz if you really need them to and the kids I can easily switch and use on my Dr Brown bottles too which has been a life saver. The bottles are super easy to wash and store and the amount they hold is true to other bottles!

My wife and I are really happy with these bottles. They are really easy to clean if using a bottle brush, and have been very durable and leak free.The main reason I'm writing this review is that the graduations seem to be slightly inaccurate. Of course these are not designed to be laboratory accurate, however if you're formula feeding it is important to know exactly how much water you're using to mix the formula. The bottles measurements slightly overshoot the actual amount of water in the bottle, so if you measure exactly to the line, you are giving slightly more water than you think. The error gets increasingly inaccurate the more you fill the bottle. Essentially if you fill the bottle to 2oz, the error is pretty much negligible, however if you fill the bottle to 8oz, the error is about 1/3oz off which is significant enough that I'd want to know about it.The error seems consistent from bottle to bottle, so it isn't likely a flaw in any particular bottle, but the design itself. That said, we still love these bottles and just compensate by filling the bottle to where it should be.

Really like these because they are bigger and can fix 8oz bottles in them. My favorite organization for bottles and sitters for the fridge.
