Helium Filaments are slender, glowing strands that emit a soft blue light, resembling delicate threads of energy. Each filament is approximately 30cm in length, with a slightly irregular, organic curvature that gives them a natural, flowing appearance. The surface is smooth with a subtle luminescence, and the core pulses faintly, suggesting contained energy. The filaments are often found bundled together, creating a small, radiant cluster that stands out against darker environments.
