Where can I buy industrial size Chalk Pastel in Singapore?

Question

I want to buy large, industrial size chalk pastel; the kind that artist Julian Beever uses for his sidewalk drawings.

I've checked Art Friend, and various other art stores in Bras Basah, but no luck.

Answer 1

Toy stores sell large, chunky, colored chalks under the generic description of "sidewalk" chalks. I have seen it sold in large buckets, or tubs with, maybe 30 or 40 colors.
