These teats are compatible with all medela bottles (note - wide-base teat is required, regular medela teats will not fit).
German made, excellent quality.  Replacement wide-base medela teats are available in both slow and medium flow rates.

Medela provide a wide variety of breastfeeding and special needs equipment; and are the leading authority worldwide for breastfeeding pumps and equipment.

Please note - the collars and discs are from medela bulk, hence will be provided in a plastic zip-lock bag (not in blister packaging).
