Their advantages compared to other products on the market are the larger capacity (250 ml) without being more expensive for the amount of milk storage and the number of pieces they provide. They are durable with easy sealing and stand upright. They do not show the exact amount of milk but this was also the case with another company. Overall, they are a value for money choice.

Opens easily. Closes well. The gauge is indicative. You write on it the amount of ml you pumped.

Very easy to use. Their only downside is that to be sure about the ml, you have to put the milk in a bottle first. The bag shows more.

Excellent bags and very high quality. They do their job well, seal tightly, and open easily when you want to pour out the milk. I used all 50 and none were defective. In fact, I donated 40 of the 50 to the breast milk bank and they accepted them just fine.

Very good and large. Safe closure without leaks and it doesn't "stick" too much milk inside when you empty it like with another well-known brand. I recommend them.

They are the only ones that fit 250ml. They have been very convenient for me from the start and are of very good quality. They stand upright without any problem. I will buy them again.
