This type of mechanical razor has been produced in the USSR since the 80s and was usually used when there was no electricity. The razor works by compressing the mainspring, similar to clockwork mechanisms. The kit includes a plastic box, instructions for use and an additional shaving head. Dear customers, I do not advise you to use the razor for its intended purpose, modern razors cope with this task much better. I will be happy to answer any additional questions.
