This is a set of two replacement blades for CARL No.120N. One pack contains one blade, and there are two packs in total. One pack has been opened but is unused. The packaging has some wear and tear due to long-term storage at home. Please understand this. Also, in my subjective opinion, the blades appear to be rust-free from the outside. (※ I cannot guarantee this for the unopened pack.) - Brand: CARL - Model Name: K-120N - Application: Replacement Blades Thank you for viewing.
