The Sensory Blocks are different shaped rubberwood blocks that contain a variety of sensory centres such as beads, clear acrylic, coloured sand and sparkling water. Colourful and tactile, your child will love discovering the different sounds, movements and colours as the light passes through the shapes, stimulating their interest and curiosity. The safe, smooth wooden exterior and brightly coloured sensory centre make these blocks perfect for children from an early age. Ideal for learning shapes and colours and encouraging observation skills, e.g. all triangular blocks are green etc.
