It is about 12-15rmb for the larger bottle.
Use it liberally, splash it on.
I splash it on to any exposed skin, including face and ears. It has an alcohol base and so it is also cooling. I also put on my ankles through the socks or any areas of tight clothing as mozzies bite through tight clothes.
Hands and feet are the areas that itch/irritate the most if bitten, and so I concentrate it there at night, so that the bites don't wake me, if bitten.
