These are solid. The bonds are a tight fit and won't come lose. I'm currently building a kit to fit my needs. I'm grateful for finding this company.
Glad we could help. For anyone wanting to replenish a model set or kit or build a custom chemical structure, our 3D Molecular Model Builder will make your task much easier.
