I really love these jars. I use them to store breast milk in when I pump and they work great. Great size, the markings on the side go up to 6ozs but the jars themselves are 8ozs. I like that the tops can be written on with a dry erase marker to keep track of when the milk was pumped and then easily wipe off. Having lids that are multiple colors too is great as I plan to use these for baby food later on when she starts eating solids.

We try to avoid plastic as much as possible and these have been so helpful. I use them daily to store breast milk in the fridge. I use them to freeze milk as well. It's a little expensive having to buy several boxes to have enough to keep them frozen as well but worth it to us to avoid plastic exposure. Now we're working our way through our freezer stash we've started using them to store puree so it's been nice to be able to keep using them.

I ordered these jars to pump into and store milk in. I really like that they have the measurement markings on the side so I can accurately track output.I hand wash the jars and they are never put into the sink with other dishes - they go on the counter until I wash them. With that said, it hasn't even been 3 months of usage and 2 of the jars have hairline cracks on the outside. It was an issue I was just going to overlook - until today. I finished pumping and realized a third jar had a circular crack on the inside of it. I ran my finger across and there's actually a chunk of glass missing. I don't know when this happened so now I can't feed this milk to my baby.For the price of these jars, this is horrible quality. I'm just glad I saw it before giving my baby any milk that possibly has glass in it!

These make breastmilk and baby food storage simple and organized. The smaller size is great for baby. They do dribble when pouring a liquid out of them (for example, stored milk into a bottle). I did not use these as an actual bottle, which I believe you can do with the purchase of the nipples.

I am exclusively breastfeeding my little one and I was looking for a good storage for when I pump when I go back to work. I tried bottles with flat tops and they leak on me. These are easy to store hold the full 8oz and no leaks. They are also easy to wash.

Great combination of sizes, and oz and ml markers are clearly marked in glass. The lids are plastic, so if you're trying to avoid plastic altogether you can use metal mason jar lids and rings instead. Mason Bottles also offer adapters for pumping directly into their jars, but we had mixed results. Love that these will continue to be useful long after we're done bottle-feeding!

We used these once and the baby bottle lids that are made to pair with these leak horribly. One of the bottles cracked in the dishwasher. Some of the lids won’t screw on correctly.

Los bottles son de muy buena calidad, las tapas traen su empaque para evitar derrames, los tamaños son muy buenos, pensé que los de 4oz serían muy chiquitos pero son ideales para meter las papillas cuando salimos de paseo, todos llegaron intactos y venían muy bien protegidos en la caja. Son un poco caros si sumamos gastos de envío y cargos por importación, pero vale la pena tenerlos y así no contaminar tanto con el uso de las bolsas

One of them was completely shattered, 2 were chipped and there bits of glass everywhere. I’ll still use the ones that survived once I can be sure I’ve gotten all the bits of glass off of them (I’ve already boiled, and washed in the dishwasher but I still feel grittiness) but I’m not loving the look of them or the quality as much as I was expecting.
