صمام دكبيل البديل لأكواب التعبير

I was worried about leaks, but these duckbill valves create a much better seal than the old ones I was using. They’re also noticeably stiffer, which makes pumping feel more consistent and efficient. Just what I needed for a smoother session.

These fit the cups perfectly and honestly made my pumping sessions way less stressful — the suction feels much more consistent than the old ones I had. Buying a set of these as backups was a no-brainer.
