Spindle Black / Premium Series SPINDLE is a work that was created when two walls were built on a slope and a spindle-shaped object was rolled between them. The spindle-shaped object descends with a pleasant sound, alternately slowly hitting the walls on both sides. The stainless steel part of Black is subjected to a special black dyeing process. The black dyeing process of stainless steel is very rare and is carried out using a special technique. Unlike painting and plating, each product shows a unique expression, and you can enjoy the change over time. Walnut is used for Black wood. Solid walnut wood of this thickness is invaluable. Using the precious wood, the woodworkers of Tsubame Sanjo carefully processed it. In the premium series, we will deliver it in a special box for GRAVIMORPH that has a luxurious feel like a wooden box, which is finished by laminating paper to a base (core material) of 2 mm thick "paper" and finishing it by a method called V-cut processing. 【Notes】 ・Use this product on a horizontal surface.
