Medela PersonalFit Flex Breast Shield L 27 mm Set of 2 One is new and unused. One was used about 3 times and has been sterilized. A midwife recommended that it would fit perfectly with Pigeon's electric breast pump, so I purchased it on Amazon. I would be happy to sell it at a low price to someone who is looking for it. Thank you. It is also listed on other flea market apps, so it may be suddenly removed. Due to shipping costs, I may ship it out of the box.
