The Osa Table Lamp is a work of art, as its surface is covered in hundreds of pieces of natural bone that were ground into picket-tile shapes before being applied. The precision required to place the pieces so perfectly is a painstaking process. The plinth base the ivory table lamp sits on is also covered in bone. Wipe clean with a soft, dry cloth or static duster. Always avoid the use of harsh chemicals or abrasive cleaners as they may cause damage to the item's finish.
