|Medela Wide Base Collar (Ring) for Bottles|
New Medela Wide Base Collar - fits all Medela bottles and new Medela Wide Base nipples. This collar will screw onto all Medela bottles but will only fit the new Wide Base nipples produced by Medela on or after May 2009. If you have the older conventional (narrow base) nipples, you will also need to order the new Wide Base Nipples.
