These 3 Cyber-Steam Punk UltraLinks with Aqua HyperGlow Inserts are a beautiful option for EDC key carry. The Leather strap fits belts up to just over 1.5" wide. Scales are Phosphor Bronze with Swiss Turn countersunk fillister head brass screws. The core pieces are day/night glow Aqua Hyperglow composite, and the spring, powder coated black is Grade 7075 Aerospace Aluminum. Only 3 of this type will be produced! Note: The black on the clip will wear relatively fast given the friction during daily use.
