Jolyn:
If I'm not wrong, you can even buy liquor, perfume, cream etc. Think they will pack it specially for you and seal it or something. To play safe, maybe you don't open the oil on the plane to use, in case you get into trouble with the immigration upon arrival at holiday destination. Wait till you reach your destination, then use. And when you fly back to SG, you can check it in your luggage.
I'm waiting for Ueno's reply too. [IMG=http://www.singaporemotherhood.com/forumboard/clipart/happy.gif]
