A leather-like titanium bracelet infused with Aqua Titanium at approximately 100 times the concentration. The top part uses pure titanium. A smart design with a large cut-out around the central joint. Considering sweat and color fading, the cord uses a leather-like material instead of genuine leather. The cords come in a set of two colors, black and brown, so you can change them to match your mood or outfit. A black, round case is included. Purchased over 10 years ago, I have only used the black one, and the brown one is unused.
