So crucial to my pumping

I’m still new to the pumping world, but I started to hear about the importance of the right size flanges for successful sessions, so I looked into it, and measured before I ordered my willow go. When I got the box I found the measuring tool in the box, and so I double checked and was able to use that to make sure I’m using the right equipment.
