The Beechwood Glossy Brown Stair (A068) is a full ten-prism set in the classic graduated sequence, crafted in polished beechwood for durability and visual clarity in a busy primary environment. It supports sensorial discrimination of thickness and size in three dimensions, and its high-gloss finish gives the prisms excellent visual contrast that helps children at the beginning stages of the work perceive the gradations clearly. This is a solid foundational choice for classrooms that want longevity and a clean aesthetic in their sensorial area.
