3D Metal Corner Protector 34mm for Trunks & Cases

3D Metal Corner Protector — Where Protection Meets Luxury Craftsmanship

Every great trunk tells a story — and the corners are where that story begins. These three-dimensional metal corner protectors are the hallmark of serious craftsmanship, the same style of hardware found on the world's most iconic luxury luggage. Compact, solid, and beautifully finished, they wrap around the corner of your case with a satisfying precision that instantly elevates the entire piece.

Whether you're building a bespoke travel trunk, crafting a jewelry chest, or restoring a vintage case, these corner pieces deliver both structural protection and unmistakable visual impact.

Design & Aesthetics

Unlike flat two-dimensional corner plates, these protectors are fully three-dimensional — wrapping around all three faces of a corner for complete coverage and a bold, architectural presence. The smooth, mirror-polished dome catches light from every angle, giving your piece a premium, high-end appearance that flat hardware simply cannot match. Available in four versatile finishes:

• Gold — Warm, radiant, and glamorous. The signature finish of heritage luxury trunks. Pairs beautifully with tan, cognac, and brown leathers, as well as monogram canvas.
• Silver — Clean, modern, and universally flattering. Ideal for black, grey, navy, and contemporary materials.
• Antique Bronze — Rich, vintage-inspired warmth with a subtle aged patina. A natural fit for bohemian, retro, and artisan leather goods with a storied, well-traveled character.
• Black — Bold, stealthy, and ultra-modern. A favorite for streetwear-influenced designs and all-black luxury aesthetics, as seen on high-end fashion house accessories.

Construction & Quality

Crafted from high-grade iron with a durable electroplated finish, these corner pieces are built to last through years of daily use. The electroplating process bonds the finish deeply to the metal surface, resisting scratches, tarnishing, and wear far better than painted or lacquered alternatives. Three precision-drilled rivet holes — one on each face — ensure a flush, rock-solid installation that won't shift, rattle, or loosen over time.

Why 3D Over Flat?

Flat corner plates protect only one or two faces of a corner — leaving the most vulnerable point, the actual corner tip, exposed. These 3D protectors wrap around the entire corner, providing superior protection against impact, abrasion, and edge wear. They also look dramatically better: the three-dimensional form creates depth, shadow, and visual interest that flat hardware simply cannot replicate. Once you use 3D corners, you won't go back.
