Unlock a universe of hands-on creativity with the DIY Xiaomi Grain Magnetic-Electric Rainbow - 510 Magnet — a set of 510 powerful, precision-coated neodymium-iron-boron magnetic beads that let you build, sculpt, and fidget your way to endless 3D designs, all without a single battery or wire.

Key Features

• Build Anything You Can Imagine — Each bead is a color-plated, nickel-coated neodymium-iron-boron permanent magnet. Their strong magnetic attraction lets you connect, stretch, and stack them into any 3D shape: animals, buildings, geometric models, or abstract art. No glue, no snaps, just pure magnetic force.
• Instant Stress Relief at Your Desk — The tactile sensation of squeezing, separating, and rearranging clusters of smooth beads provides a soothing, hands-on experience. The magnetic pull and tension create a satisfying, calming fidget that helps you focus or unwind during work or study.
• Boosts Spatial Thinking & Creativity — This is a hands-on educational toy that develops spatial imagination and fine motor skills. By hand-building creative displays, users learn about geometry, balance, and magnetic principles in a fun, engaging way.
• Premium, Durable Construction — Each bead features multi-layer electroplating to prevent oxidation and keep the colors vibrant. The surface is smooth with no sharp edges, and the magnets are powerful yet safe for repeated use. The set comes in a thickened tinplate metal storage box for easy organization and portability.
• Completely Non-Electric & Safe — Powered solely by physical permanent magnet force, this toy requires no electricity, batteries, or charging. It is a pure, screen-free play experience that works anywhere, anytime.
• Versatile for All Ages (3+) — Perfect for kids (over 3 years old), teens, and adults. Use it as a creative building set, a desk toy for stress relief, or a learning tool for STEM concepts. Ideal for home, school, office, or travel.
