Do Laianzhi KN100s still use synthetic latex?
So I remember when I looked at it years back, the ppeo website said Laianzhi HYX1002 KN100s used synthetic latex. I looked at the website again more recently and didn't see that anymore: https://ppeo.com/goods/kn100-mask/
Does anyone know if Laianzhi KN100s still use synthetic latex? If they use natural latex now, am I putting myself at risk of getting a latex allergy when I wear them for long periods of time? (Typed while wearing one right now.)
