Stones are a wonderful natural resource that children find hugely appealing. This satisfyingly smooth set of twelve tactile stones has been created to inspire children’s natural curiosity as they explore and sort. Older children will enjoy sorting by colour, ordering by size, stacking and matching whilst younger hands will simply like to hold and experience the different sizes and weights. Suitable from birth, Natural Sorting Stones are ideal for treasure baskets and sensory play activities but are also durable for use in sand, water and outdoors. Each set includes twelve stones in three different sizes and four colours. Largest stone measures 80mm.
