Advantage:
The zero-tolerance cube is made of a purity element simple substance, been through cutting and polishing, the polishing process completely removes cutting marks, and natural metal (element) color with matt surfaces.

Instruction :
These are portable and well made. Suitable for teach science classes and being able to hold the exact same size of various elements, demonstrates density and atomic weight. It can enjoy getting to see and touch the elements—this design makes them even more powerful as an education tool. It brings a portion of the periodic table to life. Each element is engraved with its density, periodic table symbol and number on one side. The other side is engraved with the melting point and atomic weight.

NOTE: Please use or touch the cube before with gloves. Keep it sealed and dry when not in use.
