The easy hold glitter panels set comes with three glitter panels in three different colors. Stimulate the senses with gold, silver and purple glitter! Children will love the bright colors and smooth surfaces. Small hands will have no problem gripping the large handholds with rounded edges. Hold the panels up to a sunlit window or a light panel to watch the sparkling colors dance. These durable panels are designed to last for years without scratching, leaking or breaking. The sound prism set features six pairs of beautiful hardwood triangular prisms, identifiable by colored musical notes on one side and a unique sound for each pair when shaken. Helps learners in their sensory development and understanding of the world through sound. Sensory reflective sound buttons feature a set of three hollow, stainless steel disks with three finishes: gold, silver and color burst. These disks will distort reality, present reflections and produce a range of sounds for a multisensory experience that will endlessly fascinate young minds. These manipulatives are hollow with no seams or holes, which means bacteria and mold cannot build inside. They're also non-porous and easy to clean. These disks are strong, won't rust and feature flattened midpoints for stacking, making them ideal for centers, schools and homes!
