2 pieces/pack, if you need other types of printer film, you can contact me to check if there is any stock.

Replacement operation:
1. Remove 8 screws to detach the steel rings from the resin vat
2. Remove the 24 screws to seperate the steel rings and change the FEP film
3. Put the new FEP film in-between the two steel rings and install those 24 screws back. Youmay need to force the screw in
4. Install the steel rings back to the resin vat and ensure the FEP film is clean and tensioned properly
