Has anyone used their pumpin pal flanges for two separate pumping journeys?

I had a baby Jan 2025 and will have my third in June. I still have my pink pumpin pal flanges and luckily they were the best things ever. Wish I found them sooner.

Are they made to last this long? I used them for about 6-7 months so they’ve been sitting in a drawer since I was about three months pregnant with this one.

They do look pretty cloudy but unsure if they would not work as well as brand new ones? I want a second pair anyway but wondering if I need a third for backup.
