Take one of the individually wrapped blades out of the 5pack box. DO NOT unwrap it from its paper packaging. First, fold it in 2 to break the blade in half, then take one half out of the paper package and place it onto the small "latches" of KRWN's blade holder. You can use them on any blade holder and also on traditional razors without breaking them in two’s.
*Use at your own risk, KRWN is not liable for any self-inflicted injuries from the misuse of our razors*
