I remember seeing this a while back. It is a compact cartridge razor. the head comes out from the canister and then tilts 90 degrees and you slide on a cartridge. Seems more bulk than it is worth especially with the disposable razors these days.
Gillette Shanghai's main importer is Procter and Gamble, ie they provide legit Gillette branded product as do Gillette's Indian and Russian joint ventures. The Shanghai company was established in 1992 as joint venture between Gillette and Shanghai Razor Blade Co. with Gillette retaining a 70% interest.
The razor was originally sold under the name "WATT MAGIC RAZOR", but it will also be renamed as Avon, Gillette, Sorone... and many other brands for marketing purposes.
It is a pity that the inventor's company has been dissolved many years ago, so what is currently on the market is mainly the previous inventory, and there is not much left.
As for the Shanghai Gillette Company, as The Gentleman said, it is the real Gillette branch, responsible for manufacturing and marketing in many parts of Asia; the DE blades it manufactures include "Super Blue" and "Super Thin".
