• Raw Polished Titanium
  Titanium is ultra strong and ultra light. It’s the world’s number one naturally occurring metal for strength-to-weight ratio. Being naturally corrosion resistant means high shine and zero rust in all conditions. Shot peened for increased strength. The color, dependent on the light, shines between silvery-white to gunmetal gray.
