HAKUZA original Pure Gold Platinum Leaf

We focused on creating an alloy of pure gold and platinum. In 2002, though considered difficult due to the difference between melting points, we succeeded in creating the alloy and developed two types of Pure Gold Platinum Leaf.
Although extremely close to being pure gold, towa color gold leaf posses a distinctive hue, due to its 1% platinum content. Koun color is close to champagne gold.
Pure gold platinum leaf is suitable for outdoor use, since it contains no substances that can cause discoloration.
