Our Montessori Wooden Education Material Pressure Cylinders set is the perfect tool for sensory development and problem-solving skills. As a factory that specializes in creating Montessori educational materials, we ensure each cylinder is crafted with high-quality wood to ensure durability and sustainability. Each set includes four different size cylinders with corresponding lids that must be matched and placed in the correct order based on the level of pressure required to push down the cylinder. This educational toy promotes fine motor skills, cognitive development, and encourages children to explore and discover through play.
