LESS THAN 600 by Knowledge Base Design


Gold leaf is produced from gold and more diverse than gold. 

The skills of Kanazawa traditional craftsmen who have accumulated over 400 years of history have been fused with ornaments and Buddhist instruments that are in harmony with that era. The light like foil that can only be made with foil is now created with new value.


Gold leaf beaten to less than 0.1μm thick reveals a bluish-green color when light is transmitted through it. Using Japanese traditional craft ”Kanazawa metal leaf” to apply gold and tin to the three shades, as they rotate, in between the gold and silvery gleam lies streams of  bluish-green as well as the new possibility of ”Kanazawa metal leaf”.
