Hmm.. Depends on where you're going. You can get white V-Cubes in Singapore, and around Malaysia there are stalls that sell things like clown cubes, YJ-2(3x3), QJ 4x4 and 5x5, PVC minxes, Super square-1's, square-1's, mirror blocks, fake rubiks snakes/twists.
If you've heard of Mid Valley Megamall in Kuala Lumpur then they have a stall there that sells all of the stuff Hyprul has mentioned. And I suggest you visit that mall too since it's one of the biggest in South East Asia, if not the biggest. Otherwise you can also find those cubes in smaller shopping complexes.
There used to be JSKs sold in Toys R' Us outlets but last I heard, they're not there anymore. There's a Toys R' Us outlet in Mid Valley so that's another reason to check that place out
There's also a guy in the Malaysian Cube forum selling V-cubes so you can check it out to find out prices and stuff
kcobe.com shop is located in N-G-8, Dahlia Apartment, Jalan Pandan Indah 24, 55100 Kuala Lumpur, Wilayah Persekutan, Malaysia. Check out the website for more detail of the cubes they sell.
