My friends are travelling to China/Thailand- What is a good "Bon Voyage" Present to get them>?

Something that they'll be able to you use there...

A sars mask and a aids prevnetion course.

A nice hat or a canvas shopping bag or sunblock.

A phrase book is the best present I was given when leaving UK for China, also just a reminder that chinese people will think they are very rich, so be carefull about being overcharged. For example,I was asked for 800 yuan for a picture, the next day a chinese friend got it for 300 yan for me.
