Our replacement OmniShaver blade cartridge package includes 4 shaving cartridges and 1 cartridge replacement tool. This cartridge kit was best designed to fit our new generation "Silver Arrow" Premium OmniShaver which has our most recently modified cartridge locks.
We worked hard to make it so these blade cartridges would also fit previously offered Premium OmniShavers (with "White Arrows") that were purchased after January of 2019...so they will fit "White Arrow" Premium OmniShavers but won't lock into their shaving head as securely as they lock into our new generation "Silver Arrow" Premium OmniShaver.
