Review: Tip: crinkle them before you put them in - These are great for the Willow 3. If you crinkle them before you put them into the case assembly it will be of great help. I watched a video in which you can use a fork to empty them out through the valve, put it in the fridge and reuse them again. They are a bit expensive but worth it if you want a 360 degree suction.
Review: Convenient and leak proof - I have the willow 360 pump and it is amazing. It really is leak proof both during pumping use with the pumps and the bags. I bartend and use this while I work. The pumps are a bit noticeable and bulky. But other than that they work amazing. And these pump bags are awesome for when you are busy and or on the go. Would define recommend the willow 360 and the pump bags that go with it

## Questions & Answers

**Q: How can i buy the 24mm bags, as the 27mm does not fit my pump correctly and waste milk?**
A: I’m pretty sure there is only one size for all flange sizes. Although I have seen bags that say they are for willow 1&2 generations but I have 3 and haven’t seen a different size to go with each flange.

**Q: Will the pump work without the bag attached - I just bought a series 1 because I could not afford 500.00?**
A: If you have the reusable flange than yes it will work without the bags but I have the series 3 so I don’t know about the series 1 and I don’t know if They have a reusable flange that could be purchased instead of bags. As long as you have the correct pieces you don’t have to use the bags for series 3. But you’ll have to check with the one you have. Hope this helps.

**Q: If I have a low supply can I put the bags in the fridge in between sessions and use the same bag for the next pumping session ?**
A: No, because you would be mixing the milk at different temperatures. This is one of the only real drawbacks for using the willow pumping bags. For a low supply, I would recommend their reusable storage containers. That way you could pump a little, pour it into a bag or container, and refrigerate it and then on your next pumping session do the same. Then mix your cold containers together to freeze if you want.

**Q: How long did it take for these to arrive?**
A: About 2 days

### ⭐⭐⭐⭐⭐ Sturdy!!
*by A***J on January 3, 2026*

These bags are so sturdy!! You don’t have to worry about spilling your milk when transferring because it has such a slow flow almost like it’s designed to reduce as much spillage as possible. I wish I could buy them in bulk! Other than that, I love these bags and they stay in rotation for my willow 360!
