Stunning Set of (6) new condition Katana Tsuba (Excellent Condition) with carrying/display case (faded from age but still very solid). I put a heavy magnetic field over all of these and did not get any draw. I'm not totally sure what metal they could be made from but typically they could be with iron, alloy, copper, bronze, etc.. Regardless its an awesome set and is perfect for the collectors. Stunning Gold and Silver accents in the raised relief design over the tops of the Tsuba and the engraving detail on the back side. Just an awesome and very interesting find. Take a look at my Ebay store for more Vintage Collectibles,Home Decor, and Fashion Accessories. Thank You and Happy Shopping!!!!
