• •Advantage: The zero-tolerance cube is made of a purity element simple substance, been through cutting and polishing, the polishing process completely removes cutting marks, and natural metal (element) color with matt surfaces.
• •Element cube blocks are made of high-density metal element cube, are safe for all ages, They are practical educational applications for different grade levels and also are great for element collections and display. Great for element collections, hobbies, DIY, experiments, and material display. The element dice can be applied for understanding metals, elements, and different density for labs, science, teachers, science, and gifts.
• •Instruction :These are portable and suitable for teach science classes and being able to hold the exact same size of various elements, demonstrates density and atomic weight. It can enjoy getting to see and touch the elements—this design makes them even more powerful as an education tool. Each element is engraved with its density, periodic table symbol and number on one side. The other side is engraved with the melting point and atomic weight.
• •NOTE: Please use or touch the cube before with gloves. Keep it sealed and dry when not in use.

Main highlights

• •PRECISION ENGINEERING: Antimony cubes are made with superior precision using cutting-edge technology, featuring crisp edges and flat cut surfaces, with a size of 10MM*10MM*10MM (0.39in), meeting the market's minimum tolerance of (+/-0.1)mm.
• •HIGH PURITY: Antimony element cubes have an outstanding purity level of 99.9%. With the color of natural metal, they restore the true texture and surface of the metal elements. They are completely non-toxic and safe for users of all ages.
• •ENGRAVED DETAILS: Element cubes are engraved with important details including chemical symbols, names, atomic number, density, purity, and atomic weight. Explore the fascinating world of elements with accuracy and authenticity.
• •VACUUM PACKAGING: Each element cube has an acrylic storage box on the outside and is also vacuum packed to ensure that the fragile cubes are protected during transportation. This method of packaging not only preserves the natural appearance of the cubes, but also prevents oxidization, ensuring their lasting quality upon arrival.
• •VERSATILITY: These Metal Element Cubes are not only suitable for density teaching purposes, but can also be a great addition to a collection. Their sophisticated appearance and the precise properties associated with each element make them ideal for classroom, office, science department, home and school displays. Unleash your curiosity and explore the wonders of chemistry.
