This listing is for all 118 element cubes. If you are creating your own large display of the elements, this is a great option! The price is discounted so it is cheaper per cube compared to the price of purchasing each cube separately.
85 of the 118 cubes have physical samples of the elements embedded within. The other 33 cubes are placeholders and have the radioactive symbol embedded within. Those 33 elements are man-made and do not exist in nature due to their extreme instability and radioactivity.
The size of these cubes is 50mm x 50mm. Please do not hesitate to contact us if you have any questions!
