Note .:
Once I was asked to a diameter, these chalks there are square and round. The first ones I got were angular. Bought later that chalks arrived around. It is therefore advisable, its commitment to value 'round' or 'square', this and if necessary to clarify the actual dimensions with the seller before buying.

The currently matching chalk holder for round Chalk is the Lyra 7166

NB. (As classified under Toys):
Crayons are for us certainly not toys because build the towers there are better :-)
