Time & Style Bridge Across features a sustainable product, and are produced by a sand casting manufacturer in Takaoka, Toyama Prefecture. The sand casting is the process of placing an original mould in a box and filling the box with sand. The original mould is carefully removed from the sand, and then the same mould is made for both the male and female dies. Those both dies are putting together into a single box. Molten metal is poured into the box. Once the metal solidifies, the external sand mould is destroyed and the metal copied the same shape of the mould. The metal then goes through the process of polishing to add shine, since it leaves grainy traces of sand on the surface.
