Two Remington R3000, R4000, R4001 head sets
This is a replacement head, cutter and frame set x2. Just pop the old top of your shaver off and replace it with this new one with a spare head set for next time.
Fit models: R3000, R4000, R4001 series shaver.
The spares consist of the outer frame with three inner foils, the cutters underneath and the retaining plate beneath them holding the cutters in place.
So to recap it comes as a whole head piece so it's very easy to replace with a spare for the future.
These spares should be replaced on a regular basis for optimum performance.
