BRAND NEW!  It is one of the accessories that came with my Panasonic ES-RT97 shaver but I have no use of it.

Also fits ES-RT47 shavers.

The wesrt47s7208 comb attachment is a versatile, five-setting comb attachment snaps quickly and securely onto select Panasonic shavers. Quickly turns shavers into a precision beard, mustache and hair trimmer, with adjustable lengths from 1.0 to 7.0mm.
