The larger size will be easier for the younger children - the increase in fees is only very minimal.
The small size is 5" x 7", while the large ones are 6.5" x 9.5".
We are also in the midst of switching the Sand from a local brand to a US-brand - the visual effects are stunning!
We are constantly looking at ways to innovate and re-invent so our customers can benefit!
