The Pro-Staff Elite XXL Edition is made out of Elk Antler, Exotic Ebony and has a Dual Gold nugget inlay. Also featuring a titanium band for strength and durability. This band is a 1/2” wide or 12.7 mm. Please be sure to get sized for a 12.7 mm wide band, as wide bands fit much tighter. I was skeptical on the comfort of this band being so wide but after wearing it, I was pleasantly surprised on the comfort. This design can be made in sizes 8-15 If a bigger size is needed please email me. All sales final.
