الوصف

【HIGH DENSITY】: Copper cubes are made of high density metal elements, non-toxic, safe and reliable, purity up to 99.95%, size is 25.4*25.4 1 inch cubes, vacuum packed to keep the natural appearance and prevent oxidation. CONVENIENT STORAGE: Provide a small 1-inch acrylic storage box to keep individual elements separate and prevent reactions between different elements. At the same time, better protect the element cubes from surface scratches. 【LASER ENGRAVING】:The copper cube metal with laser marked information on the surface, including: atomic number, chemical symbol, name, density, atomic mass,purity. It can help you to learn better about the original elements. 【RELIABLE MATERIAL】: Metal samples cubes are made of high density copper element cube, safe and reliable, which are practical educational applications for different grade levels, also are suitable for element collections and display. 【WIDELY USED】: Copper cubes can be used in labs, offices, science rooms, teachers, gifts, science demonstrations, suitable for different ages, good understanding of metals, elements, different densities, can be placed in the classroom to stimulate students' interest in chemistry, can be collected as artwork.
