Kirk here with a share from Kuma Visit. If you’re not familiar with the page, please check it out, particularly if you’re interested in the arts. And don’t be intimidated by the Japanese text you see toward the top. If you scroll down just a little you’ll be able to read English explanations.
Personally, I’m a fan of Higo inlay (Higo zogan). It has traditionally be used to decorate sword guards and other very Japanese items but I like Higo zogan necktie clasps and other accessories that men and women can enjoy in modern settings. They make great gifts.
