I stopped by my local Coach store and chatted with a very friendly SA, who showed me the leather treatment they use as a final coat in their 7-step restoration process. He said they use it for reaching perfection in appearance of restored purses and sealing in moisture. I took a picture of the jar and tried finding some info about it online, but wasn't very successful. Since its made in Japan, looks like Asian customers are more familiar with it. The only info I found was that it only contains natural ingredients - jojoba and other waxes, and doesn't contain silicone. It looks like a yellowish-clear mix of jelly and caviar-like grains; the name of the site on the jar is www.columbus.co.jp. Couldn't find anything about it here on TPF... Is someone familiar with it?
