Insert pour S9 Pro / S12 Pro

So for starters these can be used with the elvie og wearables without having to alter a lot of other companies sell specific expensive flanges and these right here a little pricey since it's 10 dollars for one but you can really use them with the baby buddah, elvie og, not the stride i found i was still having to pump with a different to empty i used with the s9pro and worked great and with the s12 not really with the medela pump in style or the hand pump i found these didn't really shine with the medela but definitely a great product probably not for the price for but definitely worth it since i use a variety of pumps for on the go and at home, travel etc.
