🎨 Choose Your Finish: Two Expressions of Titanium

• 🌌 Aurora (The Art Piece): Features a stunning, color-shifting crystal finish created through specialized annealing. Like a kaleidoscope, it changes hues from deep blues to violets under different light. Perfect for: Gifts, Office, and Collectors.
• ❄️ Frost (The Purist): Showcases the raw, crystallized texture of pure titanium. Understated, rugged, and naturally grip-friendly, this finish hides scratches and stands up to the elements. Perfect for: Outdoor, Camping, and EDC (Everyday Carry).
