High-Precision Magnetic Positioning Points: Designed with inner Ø6mm / outer Ø10mm precision dimensions, includes portable storage case (100-piece standard set), highly compatible with mainstream 3D scanning equipment. Eco-Friendly & Reusable: Strong magnetic base ensures secure adhesion, withstands vibrations from device movement without detachment. Unique soft-magnetic material enables non-destructive attachment/detachment-leaves no residue or surface damage, ideal for precision instruments and delicate workpieces. Effortless Position Adjustment: Magnetic adhesion supports real-time repositioning. Easily add/remove markers during scanning to flexibly adapt to complex curved surfaces. High-Reflectivity Performance: Multi-layer composite reflective coating ensures reliable scanner recognition even in low-light environments. All-Scenario Professional Solution: Suitable for reverse engineering, quality inspection, cultural relic digitization, and other specialized applications.
