Summary - includes space-filling models that simulate the true shape of saturated compounds; provides open models that form realistic single, double, and triple bonds - even strained rings; allows smooth rotation of the bonds to make conformational analysis easy; contains enough components to create several models at once; the components are precision-tooled from quality plastics, are virtually indestructible, and come in a sturdy plastic case for easy storage; provides a useful Instruction Book - with photos, diagrams, and concise discussions of chemical principles.
