Antique Gillette butterfly safety razor. This is a “G1000” model, descendant of the Slim Twist range. Made in the UK for the European market.
Extremely mild razor, it’s perfect for beginners and women’s shaving. One-piece system (TTO = Turn to open) : turn the knob at the top of the handle to open the head and slide in a double-edged safety blade (standard size). Close it the other way round and you’re ready to go!
This razor is NOS (new old stock), still packed in its original box which has a few defects, visible in the photos.
