Rhombohedral graphite is a thermodynamically unstable allotrope characterized by its ABCA stacked graphene layers. This structure can be modelled with this kit because the carbon-carbon bond lengths are identical to the hexagonal form.
Compare this sideview of beta graphite ABCA stacking to the ABAB of alpha graphite.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (scroll down to see "Skeletal (Orbit/Minit) and are compatible with every molecular model kit we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
The interlayer bonds are flexible to allow the layers to move showing the weak van der Waals attraction which is a basic property of graphite.
