You are buying an aftermarket part made by Maymom, not by the original Dao Health Company who has brought the Freemie hand free milk connection cups to you.
The Maymom Valve replacements for Freemie Collection Cups (sold separately) are spare parts for lost, worn out or damaged valves for Freemie Hands Free, Concealable Collection Cups. Valves that appear to be wide open in a relaxed state, or torn, may contribute to milk backing up in tubing and/or decreased or ineffective suction, and should be replaced. With proper care, valves should last for two months or more with regular use.
