Thank you for visiting the page! Ships with careful packing from Japan. The best-selling HGS molecular structure model has been re-released. This set is designed for organic chemistry researchers and includes a wide variety of balls and bonds to meet diverse needs. It allows for the assembly of basic organic compounds, as well as complex molecules such as chain polymers and steroids, and even simple coordination compounds. The bonds are highly elastic, making it easy to create double bonds, triple bonds, as well as three-membered rings, four-membered rings, and special condensed compounds.
