A sample of Scandium metal in the form of a 10mm machined cube . Purity is 99.9% You will receive one cube with each purchase. These cubes vary slightly in size between about 9.5-10mm on the sides so these aren't considered true standard density cubes. Some surfaces have slight blemishes/pitting. The weights vary from 3-3.1g as well but they still make for attractive and interesting Sc samples.
