We offer a two-thirds scaled version of the Tetrad Shelving called the Tetrad Mini. This more precious size mimics the full-scale version with the exception that the beveled edges and inside faces are fashioned from a finely layered 1-inch Baltic Birch. In keeping with our desire to develop green products, we use an FSC certified Baltic Birch and then apply a walnut veneer with a water-based adhesive. Reversible and interchangeable, these sturdy blocks will provide for endless stacking configurations and a lifetime of enjoyment.
