1 LIVELY COLORS: The molecular models are made of colorful PP balls and connection keys that are bright, well-designed, and highly durable. The standard color used for each atom makes it easier to use and learn. 2 3D MODELING: Molecular models demonstrate basic molecular geometry, chemical molecular structure, and stereochemistry through 3D model studies. It can display chemical structures, molecular bonds, and bond angles in all directions. 3 BUILD MODELS: The chemistry molecular model set can be used to build models of various common and somewhat complex C, H, O, N, and organic molecular structures for teaching and laboratory use. 4 EASY TO LEARN: The organic chemistry model set is easy to learn, easy to store, and easy to carry. Atoms and chemical bonds are tightly and securely connected and can be easily disassembled with a connecting tool. 5 APPLICABLE: The chemistry model set is used in chemistry books for the structural representation of various inorganic and organic substance molecules, which can increase students' learning interest and allow teachers to explain more visually.
