I don't know about any, but perhaps you can ask on the facebook group Deco-den: https://www.facebook.com/groups/30667815752?ap=1
There seem to be some people from Malaysia around there who would know the answer to your question.
I do know other ones like Sophie & Toffee in Singapore. http://sophieandtoffee.com which ship to anywhere in the world.
You can always take a look at craft stores in your neighbourhood, most of the time they also carry air dry clay and polymer clay in their shop!
Good luck!
