A statement piece if there ever was one! What sets our shelf apart is our refined design, quality materials, & top-notch craftsmanship. We based our design on Manfredo Massironi's Tyco for Nikol, International, Italy, 1970. Our shelves are truly handcrafted. There's no CNC. Each one is handmade to order in our home shop in Michigan. Our meticulous finishing process entails multiple stages of sanding & applications of high-tech durable finish. The unit arrives as 14 separate pieces that fit together. No tools or hardware are needed. Keyhole hanging hardware is already installed on the back of the unit, & the wall anchors are included as well. We can accommodate custom paint colors, wood species, & stain matching.
