There is an art shop (shop lot) in bandar sunway behind my college, The One Academy which sells them for rm6 each.

but the pantone markers for skin is no longer in stock ):

The old limkokwing building has an art art shop which sells them too for around the same price. (shop lot also)

You can buy the basic colours and as you need only then you buy the extra colours for a wider range cause it can be very expensive if you buy all one shot T^T


all the best!
