Just let me add, this razor is disassembled and reassembled, cleaning not included, in less than one minute.
UNLESS... you also want to put that half-open metal ring stopper (what is that thing called) back inside the handle, THIS then turns it into some 15-20 minutes of despair, effort, self-doubt till you finally forced it back in... but with a lot of feeling.
The leftmost piece, that ring on it. If anyone finds a clever way how to bring it back into the hollow handle, that would be appreciated.
P.S. the razor also works perfectly without it, the lower end can fall off when you unscrew it, so it is kind of a safety one might not deem necessary.
