The Portal2 Titanium Carbon is, as you can imagine, the follow-up the exceedingly popular Portal ring series. The Portal2 Titanium Carbon however implements the new Badgerite lume in milled side-channels instead of the solid inside layer. This allows for far greater performance and durability. A solid titanium core boasts a central insert channel of solid carbon fiber composite and the flanking Badgerite lume channels. Badgerite is powered by Swiss Super-LumiNova (r) Several colors of glow are available, so email me direct at James@blackbadger.se with your requests or questions.
