Feature 1VIBRANT COLORS: Molecular models are made up of colorful PP balls and connecting keys that are brightly colored, well crafted, and very safe from breakage. The common standard used for each atomic color makes it easier to use and learn. 23D MODELING: Molecular models demonstrates basic molecular geometry, chemical molecular structure and stereochemistry through 3D modeling studies. It can display chemical structures, molecular bonds and bond angles in all directions. 3BUILD MODELS: Chemistry molecular model kit can be used to build models of various common and slightly complex C, H, O, N, and chemical organic molecular structures for teaching and laboratory use. 4EASY TO LEARN: Organic chemistry model kit is easy to learn, easy to store and easy to carry. Atoms and chemical bonds are tightly and firmly bonded together and can be easily disassembled with a disconnecting tool. 5APPLICABLE: Chemistry model kit is used in chemistry textbooks for the structural representation of various inorganic and organic substance molecules, which can enhance students' learning interest and teachers can explain it more visually.SpecificationItem Type: Chemistry Molecular Model KitMaterial: PPStorageBox Size: Approx. 17.3x10cm / 6.8x3.9in .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List54 x Atoms30 x ShortBonds12 x LongBonds1 x Storage BoxNotePlease allow some error due to manual measurement.
