Product Description Designed by ZacLab, the Economy Class features a translucent PEI base with an amber-like texture, accented by brass and stainless steel components and enriched with natural material patterns. The cool, rigid feel of metal contrasts beautifully with the warm resin, blending industrial sophistication with organic aesthetics. A transparent window in the center allows you to watch the buckyballs bounce along the track, delivering strong tactile feedback and an ultra-smooth hand feel with every push. The interaction is engaging and visually satisfying, designed for hands-on enthusiasts. Please note, the magnet-based mechanism produces a loud crackling sound, making it less suitable for quiet environments. With extended use, the track may darken and requires occasional disassembly and cleaning to maintain optimal performance. Specifications: Size: 58 x 18.5 x 9mm Weight: 21g
