PRODUCT SPECIFICATIONS: Cubes feature laser-marked information including atomic number, chemical symbol, element name, density, purity, and nuclear data. HIGH PURITY: 99.99% pure elemental substance. Ideal for element collectors, DIY projects, science experiments, and material display. PRECISION ENGINEERING: Cubes are non-toxic and safe for all ages. Manufactured with advanced techniques to ensure crisp edges, flat surfaces, and tight dimensional tolerance of 0.1 mm. BEAUTIFUL APPEARANCE: Metal cubes are precisely cut and laser engraved with clear markings. Vacuum packaging is used to minimize oxidation. Each cube comes protected in a transparent case. MEANINGFUL GIFT: Suitable for classrooms, offices, science labs, homes, and schools. Encourages understanding of metals and elements, and allows hands-on experience with different densities. ABOUT THE CUBES: Color: Natural metal finish. Some cubes have polished surfaces, others have anodized coatings. Engraving: Double-sided laser engraving. One side displays element symbol, name, and density; the opposite side shows purity and atomic weight. Element collection can be engaging and educational. Displaying a periodic table with real element samples is a common practice in educational institutions and among science enthusiasts, often serving as a conversation starter. EDUCATIONAL USE: Supports a wide range of learning applications across various academic levels, including chemistry, physics, density studies, specific heat experiments, and scientific research. Suitable for science education projects and hands-on activities in engineering, robotics, aviation, chemistry, physics, biology, and geology.
