Solid Brass Marbles 8mm (20 pcs) for Marble Machines, Runs, Patina Finish
$12.95
Upgrade your marble machine experience with these stunning, high-quality solid brass marbles!
While all of our marble machines come with standard stainless steel balls, these 8mm brass marbles are the perfect add-on for anyone looking to add a touch of classic elegance, a distinct sound, and a beautiful visual contrast to their favorite mechanical sculptures.
✨ Why Choose Brass Marbles?
Premium Aesthetic: The warm, golden glow of polished brass looks absolutely mesmerizing rolling down wooden or metallic tracks.
Unique Sound: Brass has a slightly different density and resonance than stainless steel, giving your marble machine a richer, warmer, and more satisfying "clink".
Perfect Fit: At exactly 8mm (~5/16"), these are precision-engineered to run flawlessly on all of our marble machine models without jamming.
Beautiful Patina: Over time, natural brass develops a gorgeous vintage patina, making your machine look even more like a timeless piece of art (or you can easily polish them back to a high shine!).
