Listen To Alex's Story With the CozyCore
I was so SKEPTICAL
I have an active job and can’t afford to take days off for menstrual pain. Painkillers upset my stomach, so I tried CozyCore by Fempeir. It’s discreet, eco-friendly, and offers soothing heat that eases pain even after turning off. Unlike adhesive heating pads, CozyCore is skin-friendly and avoids the discomfort and wastefulness of adhesives. Longer battery life would help, but it’s been a game-changer!
