Unleash unlimited creativity with the DIY Xiaomi Grain Magnetic-Electric Rainbow – 510 Magnet, a 510-piece magnetic bead set that combines powerful neodymium-iron-boron magnets with a smooth, safe design for endless 3D building, stress relief, and hands-on learning — all without a single battery.

Key Features

  • Build anything you imagine with powerful magnetic beads — Each bead is a color-plated, nickel-coated neodymium-iron-boron permanent magnet. The strong magnetic attraction lets you connect, stretch, and stack beads to create animals, buildings, geometric models, or any free-form 3D shape. The beads feature multi-layer electroplating to prevent oxidation, ensuring long-lasting performance and a vibrant rainbow finish.
  • Enjoy a soothing, screen-free stress-relief experience — Squeeze, separate, and rearrange clusters of magnetic beads. The tactile sensation of magnetic attraction and tension provides a calming, meditative effect that helps reduce stress and improve focus — perfect for desk breaks or quiet time.
  • Develop spatial imagination and creative thinking — By hand-building 3D structures, users enhance spatial reasoning and problem-solving skills. This hands-on educational toy transforms abstract concepts into tangible creations, making it ideal for STEM learning at home, in classrooms, or during playdates.
  • Safe, smooth, and built to last — The magnetic beads have a smooth surface with no sharp edges, thanks to multi-layer electroplating. The set includes a thickened tinplate metal storage box for durable organization and portability, plus a colorful cardboard outer packaging that’s ready for retail shelves.
  • No batteries, no charging, no mess — This toy is completely non-electric, relying solely on permanent magnet physics. There are no circuits, batteries, or charging required, making it a clean, quiet, and maintenance-free play option for kids and adults alike.
