I need help with kpop sleeves

Hi!! I recently started getting back into collecting photocards and I had bought pvc free sleeves a long time ago but I recently ran out so I bought knew ones from shein bc they were cheaper... and I didn't have money for other ones but I found out that there's a chance it might contain pvc.😞 idk what to do because I spent money on it... 😞 is it fine to use it for trading and just letting the other person know?? Or should I just completely stop using them. 🥲
