I just got back from a trip to Tokyo and I,too, was given some m ch smaller samples of non-lathering shave stuff. It was branded Schick and it worked pretty well.Best non-lathering gel I ever used was a small complimentary tube in a hotel in Tokyo. I believe it had aloe in it but that's all I remember. It was unscented...and didn't take much, the tube lasted me a week and it was the best shaves I ever got with a twin blade cartridge.
Unfortunately this was in about 1999 so I have absolutely no recollection of the details. But it made an impression, that's for sure.
So I went to a store and purchased a container of it for future travel needs. I bought one labelled Premium, and it turns out it was not the same stuff. This stuff is completely clear and a bit gelatinous, but it is very slick and shaves great. Has a nice, light scent to it, too.
The complimentary two-bladed disposable razor they handed out is a Kai, and it is better than any disposable razor i've ever tried.
They definitely get better cheap stuff in Japan than we do here in the states. I think the container of shave gel I bought was about 5 US dollars.
