I've never used KGD but I tried Muji and thought it taste like crap. Stuff is all over out here, I prefer these little pads they sell at 7-11 out here. Wife has some Chanel cotton I might try.
Those pads are pretty much the same thing as Muji, lol. Muji means no name or brandless, they are kinda like the Japanese version of walmart. They sell whatever at the lowest price possible.
Also the KGD that was started by a Japanese actress. So none of us really know the quality of any of this stuff really, lol.
