10 PCS Elements-Cubes - Density-Cube Set As Shown 0.39 Inch/10 mm for A Periodic Table of Elements Collection

These cubes make a beautiful paper weight or educational tool. I bought them for my brother who is a scientist and he loved them. The density’s are accurate and the design is simple and tasteful.

Quick delivery, as described..

The cubes are quite small, but also inexpensive. It's great for showing kids the impact of density, going up to Tungsten (nearly same density as gold). Would recommend
