【SHARP Genuine Product】 Disposable Pre-filter - Model Number: FZ-PF51F1 - Compatible Models: FZ-PF80K1, FZ-PF70K1, FZ-PF80F1 This is a genuine SHARP product, brand new and unused. I purchased it but no longer have a need for it, so I am selling it. Please note that I will be sending it in an envelope, so I will try to minimize the thickness when packaging. I hope you find it useful.
