Feature 1EXQUISITE AND DURABLE: This molecular model is composed of colored PP balls and connecting keys, with bright colors, sophisticated technology, easy to use, durable 2MAIN FUNCTIONS: Molecular model kit can stimulate children interest in learning, exercise hands on ability and expand spatial imagination 3TEACHING AIDS: The spherical molecular structure model can be used to describe the structure of various inorganic and organic substances molecules in chemistry textbooks, which can be interpreted more intuitively by teachers. Very convenient 4SAFE AND ENVIRONMENTAL PROTECTION: The molecular model kit is made of environmental protection pp material, which is very safe and will not be broken, and has a long service life 5APPLICABLE SCENARIO: This model set can be used to construct all kinds of common and slightly complicated C, H, O, N, chemical organic molecule structure model, applicable to teaching and laboratory 63D CHEMISTRY EDUCATION MOLECULAR MODEL: Chemical structure, molecular bonds and bond angles can be displayed in all directions. Demonstrate basic molecular geometry, chemical molecular structure and stereochemistry through 3D modeling research 7EASY TO LEARN: The common standard for each atomic color makes it easier for you to use and learn. The atoms and bonds are tightly and firmly held together and can be easily disassembled with the disconnect toolSpecificationItem Type: Molecular Model KitMaterial: PPSize(LxW): Approx. 23.5 x 17cm / 9.3 x 6.7in .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 List50 x Atom1 x Storage Box1 x Open Proportional Key Wrench16 x Extra Long Keys26 x Double Keys32 x Short Keys
