My lady colleague ask me to buy for her, not sure if this is good, but according to her, it is effective. Not cheap, they have one made in Japan, and another type, made in China. The former is about JY600 per pc.
I am simple person, and likes traveling and meeting people. I believe and trust on Human rights and this must always be respected. And one has to have the freedom to express his/her opinions accordingly. And live life to the fullest。 要活得精彩。。。。。
