@Abby it’s the same size as my other pumps, 24. Do different brands vary in size?
You may need to measure your nipples and order some flange inserts
@Erin yeah 24 is usually too big for most people i’m using a 19mm flange i’m sure if u have a look online u may be able to find some that’s compatible with it pump
is it the correct flange size as i had the wrong size and it was sore as it was causing my nipples to swell cause it was to big
