Embrite™ is a resin-based, glow in the dark material manufactured by our friends at TEC Accessories in Queen Creek, AZ. It has a long-lasting glow (up to 12 hours), can charge from a variety of light sources, and has almost no degradation, making it perfect for a pen built to last a lifetime. We started with the Lime Green and added Orange – both of which look great with the lights on and even better with them off. Paired with DLC Titanium, OD Green Anodized Aluminum (orange), or Light Gray Anodized Aluminum (Lime) bodies.
