Medela - Nipple Tunnel - 24 MM
Nipple Tunnel - 30MM
A necessity for the average person
I needed to buy a larger size than included with the pump. It made pumping much more comfortable and successful. I only wish that you didn't need to buy each size separately. It is hard to know which size to choose.
more comfortable than the original one
The shape is better
edges are smoother
it's a bit shorter too so it's alot more comfortable than the one I got with the pump. It came with the 24mm
which was fine for me to use. But these 21mm are even better.
