Stockmar Block crayons, available in 32 colours, although we will try all colours may not be available all the time.
The Block crayon is a good size and the flat shape means they sit well in the hand and are specially suited for small children. What is more, children can draw colourful areas easily, and arrive at interesting effects. For example by dragging the long edge of the block in a wave-like fashion across the paper.
Tins of 8 and 16 are available, also available as stick crayons
