Medela Breast Shields - 21mm

I bought these on Amazon thinking I needed the smaller size (this is the smallest breast sheild Medela makes) but I actually needed an even smaller size.

These would be great if you already have them to have as a second set (less cleaning!)

Sanitized, used a few times, and re-sanitized

I believe these fit on all Medela breast pumps but definitely fit the Freestyle which is what I have.
