Premium Material---The molecular model set is made of durable, safe, and non-toxic materials that are wear-resistant and not easily damaged. Designed for long-lasting use, this product maintains high gloss and smooth texture without frequent breakage concerns. Product Feature---This organic chemistry model helps chemistry learners understand three-dimensional molecular structures in the microscopic world. It is an essential tool for children and students studying chemistry. Precise Chemistry Model---This comprehensive model set includes all necessary components to conduct experiments. For teachers and parents, it provides an effective way to teach students or children about complex molecular structures more clearly than textbook images alone. Powerful Function---The set includes connectors representing C, H, O, N, Br, and other elements, along with various single, double, and long bonds. It supports the construction of most organic and inorganic molecular structures used in high school and university chemistry courses for experimental study. Electron Orbital Model Kits---The product includes additional electron orbital models suitable for advanced chemistry education. These enhance hands-on learning and improve understanding of molecular bonding, making them valuable for students and children.
