We tried sidewalk chalks last week after I made this purchase.
This box is available at Toy R us for RM39
Each chalk is about the size of a giant marker which makes it more durable than regular chalks.
The colours are heavenly..
This is an optical illusion shot which looked as though Tiger was writing.
Actually, he just doodled all over ^.^
We did this in the evening, so he got distracted by the birds..
