The manufacturing process aims to maintain the wood's inherent curves and lines. The finish is described as "polished imperfect," suggesting a smooth surface that retains natural wood variations. The PI wall shelf offers a horizontal surface for placing objects. The name "PI" relates to its design philosophy of preserving natural wood features.
